library compiled using g++ causing problems

["SRINATH,VIJAY (HP-India,ex2)" <vijay_srinath at hp dot com>]

hello all,

    I have a small java test program that calls a native jni function. The
jni function just throws an exception and has a catch clause which prints a
message. But when the exception is thrown, the jvm crashes. Control never
reaches the catch clause.  Iam working on AIX 4.3.3 platform and using java
1.3.1. 
      I found that this crash happens if i build my native library using g++
(i use gcc version 3.0.3). The program works fine if i use the IBM compiler
- xlC. .
Is this a g++ linker error ? (something to do with any default libraries it
links ?) 
       Is there any workaround or fix for this ? 

       I have pasted the native stack details below: 

  <snip> 
  SIGABRT received at 0xd0013ff0 in /usr/lib/libpthreads.a. Processing

To build the library, i use the command:
g++ -shared -o libjniTest.so jniTest.c -I/opt/java/include -I

                Any help most appreciated....
