Hi,

I have a program mytest.c which is calling JNI_CreateJavaVM. I am
using gcc 3.4.6. During my compilation I am adding the libgcj.a
library to the compilation because I want the libgcj.a to be a part of
the main application. I am using the below command to compile.

gcc mytest.c libgcj.a -o mytest -ldl -lm -lpthread

This compiles correctly but the application crashes and I get a
coredump as below.

This works fine if the libgcj is loaded as a shared library. Can I not
link the libgcj.a into the application while compiling ?
