Re: libgcj failure on ppclinux?

Hi,

I haven't heard back yet from Mark Mitchell, but if someone wants to try
to reproduce it I have the attached little test case that was extracted
from the preprocessed posix-threads.cc file.

mark@multatuli:/tmp$ /home/mark/src/gcc33/obj/gcc/xgcc
-B/home/mark/src/gcc33/obj/gcc test-case.cc 
test-case.cc: In function `void _Jv_ThreadRegister()':
test-case.cc:20: internal compiler error: in int_mode_for_mode, at 
   stor-layout.c:295

It compiles on x86, but not on powerpc.

Cheers,

Mark

      }
