[LLVMdev] Fwd: Building VMKit

[Joshua Warner]

Hi Minas,

I tried recompiling Classpath with -fno-omit-frame-pointer, and now, instead
of printing an error message, j3 just segfaults in
"j3::JnjvmClassLoader::loadClassFromAsciiz(char const*, bool, bool) ()"

I ran llcj under strace and found that it is not even opening the input or
output files, but is otherwise running normally.

Updating to the latest SVN version (revision 108831) didn't change anything
(I was only a few days out of date).

I'm not sure where to go from here.  Does this fit with any of the known
problems under 64-bit linux?

Thanks,
Joshua
