I have made some changes to dalvik jit by changing the jit table structure from chained array to a combination of hash table and B-tree. Now when i execute a sample java program which is
public class prog {
public static void main(String args[])
{
long start=System.currentTimeMillis();
int sum=0;
for(int i=1;i<10;i++)
{
for(int j=0;j<10;j++) {
long h=getKey();
System.out.println("key : "+h);
}
}
System.out.println("time : "+(System.currentTimeMillis()-start));
}
public static long getKey()
{
Random rand=new Random();
long key = rand.nextLong();
if(key<0)
return -key;
else
return key;
}
}
using dalvikvm -cp prog.jar prog after pushing libdvm.so(built after changes made to JIT) into the android emulator. Sometimes the program runs perfectly and sometimes it results in segmentation fault. When I checked the logs this is the error shown :

what could the possible problem be? Is it memory related problems or bug related to JIT code changed?
Thanks

Is there a way to get more useful information from an android crash? Deliberately inducing a UAF crash in android ICS I get the following output to my logcat, but is there a way to do a more complete stack dump and heap dump at the time of the crash? I can't seem to do it in ddms because as soon as the fatal signal is hit ddms abandons the process (because it doesn't exist anymore)

You can see the complete logs of the device by selecting All messages(no filters) option in Logcat.
I have the following Project I am working on. I am trying to do a simple 2D TriandleFan box.
However, when I run the project the following line fails...
this->display = display;
I can't see why it is failing can anyone else see it?

Greetings to everyone!
I'm trying to compile pjsua using the following branch:
http://svn.pjsip.org/repos/pjproject/branches/projects/android/. I've
tried to do a push (adb push pjsua /data/local/) to my Android-sdk
emulator but, when I've tried to execute it via adb shell, the Android
LogCat gave me the following SIGFAULT error: where am I wrong? Thanks
in advance.

EDIT 1: I must remark that I already know solutions such as csipsimple. Anyway, I'm interested to resolve my cross-compiling issue with Android-ndk's tools.
Why not trying to use an android device instead?
I red in the android website that the android simulator is usually not compatible with sip stacks.
I've modified the jukebox example to run on Android, but it segfaults miserably when trying to call the sp_session_create() function.
Basically - I have a helloworld Android app with a button. When pressed it calls this function, which crashes on sp_session_create():
JNIEXPORT void JNICALL Java_com_holidaystudios_unispot_uniSpot_prepareSpotify() {
sp_session *sp;
sp_error err;
const char *username = NULL;
const char *password = NULL;
username = __USERNAME;
password = __PASSWORD;
g_listname = __PLAYLIST;
UNISPOT_DEBUG("prepareSpotify() - 1\n");
audio_init(&g_audiofifo);
UNISPOT_DEBUG("prepareSpotify() - 2\n");
/* Create session */
spconfig.application_key_size = g_appkey_size;
UNISPOT_DEBUG("prepareSpotify() - 3 %d, %p, %p (%p)\n", g_appkey_size, &spconfig, &sp, sp_session_create);
err = sp_session_create(&spconfig, &sp);
UNISPOT_DEBUG("prepareSpotify() - 4\n");
.
.
.
Here's the logcat output which shows the segfault:
I/UNISPOT|NDK( 5951): prepareSpotify() - 1

Any ideas?
I'm posting this as an answer since it seems I need more reputation to answer comments, but, to answer #KurtCobain's request: you also need to make sure that your cache_location and settings_location point to a valid, writable location on your android device. The default value in the spotify examples for those variables is "tmp". This won't work and will cause your app to crash.
Instead (at least as a temporary, straightforward solution) you could use something like Context.getCacheDir in your activity to retrieve a valid temporary folder, and use this value in your C code (see this question for more info on that).
I finally figured out what the problem is. If your AndroidManifest.xml does not request the INTERNET permission (and possibly WRITE_EXTERNAL_STORAGE) it will crash... Unfortunately libspotify does not perform any checks on creating sockets and will therefore crash... I'd say it's actually a bug in libspotify... But anyhoo - here's what you need to add to your AndroidManifest.xml if you are having the same problem as I did:
<uses-permission android:name="android.permission.INTERNET" />
Possibly also this:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I have changed the structure of the JIT table (pJitEntryTable in /
dalvik/vm/Globals.h) from a chained array(sort of hash) to a
combination of hash table and B-tree. It finds hashed value based on
PC and enters the corresponding JitEntry(dalvik address,translated
address) into the b-tree pointed by the hashed index. I built the code
successfully and pushed libdvm.so file into the emulator and rebooted
the emulator by killing zygote. But the boot screen is showing
"android" for infinite time and when i did a $adb logcat i found the
following log

I don't understand the error. Do i need to make any adjustments to the
jit code cache size and heap size? Any help regarding this will be
appreciated.
Thanks
This is a segfault crash. Something is trying to access a segment of memory that hasn't been allocated, or it is otherwise not allowed to. This most likely indicates a bug in the libdvm changes that you made.
Debugging will be tricky. What I would try is to build a libdvm_new.so and dalvikvm_new binary that links against it, and push those to a device/emulator (rather than replacing the existing libdvm.so and dalvikvm) and then use gdb-server and gdb to debug dalvikvm_new, on a command line type program (the typical static void main(String[] args) type program).
