Subject: Garbage collection segfault in OpenIndiana

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?

// File: invoke.c
// Compile with:
// gcc -g -m64 -o inv inv.c -L<prefix>/lib/amd64/gcj-4.6.2-12 -ljvm \
// -R<prefix>/lib/amd64/gcj-4.6.2-12 \
// -R<prefix>/lib/gcc/i386-pc-solaris2.11/4.6.2/amd64
// The -g -m64 is optional, of course. The last -R should not be
// neccesary but is on my install.
