Hi,

> The following code using OpenMP pragmas , when compiled with gcc 4.5 + LLVM 2.8 + DragonEgg 2.8 and ran, produces segmentation fault.

I just tried it on x86-64 linux with latest dragonegg from svn, and it executes
fine, with no valgrind complaints.  After compiling at -O0 valgrind does say

==7251== Syscall param exit_group(status) contains uninitialised byte(s)
==7251==    at 0x4ED8598: _Exit (_exit.c:33)
==7251==    by 0x4E674A4: exit (exit.c:93)
==7251==    by 0x4E4CD94: (below main) (libc-start.c:258)

but that's because you forgot to return a value from main, so rubbish is
returned as the exit code.

How did you build the program and on what platform?

Ciao,

Duncan.
