Hi all,

With GCC 4.6.2 on OpenIndiana 151a (Solaris) the boehm gc segfaults in
os_dep.c:810 when JNI_CreateJavaVM() is called.  The attached
invocation example (as small as I think I can make it) is a complete
example.

Is this the right place to discuss this issue?  I thought of merging
boehm gc 7.1 into the gcc source tree, but this seems non-trivial.  In
particular it's not possible just to make it a drop-in replacement.

Is there a way to have GCJ use a system supplied boehm gc?
