Thanks for the fast reply, I tried it also on Linux Mint 64bit, gcc version
4.6.1. Same result.. (SIGSEGV) but faster (I get it in under 1 sec). I also
tried it on a CentOS 6.2 with gcc 4.4.6. gomp_loop_static_start() gets called,
with parameters like => chunk_size=140737488347560, istart=0x7fffffffe1b0,
iend=0xca. The last one is a pointer which gets dereferenced.. hence getting
the SIGSEGV.
I think it's not a LLVM bug.
