Yes, but the same occurs without gomp and pthread and regardless of if 
the build is shared or static.  I first noticed this about 6 years ago 
with 64-bit builds on Solaris x86.  At that time, AMD64 FreeBSD had 
the same problem but the issue went away so something changed to fix 
it in FreeBSD.  The problem is evident under Solaris 10 and 
OpenIndiana.

This is the behavior I am seeing with your patch applied under Solaris 
10 with self-built GCC 4.7.1 and using the Sun linker.  Based on your 
description of why things fail, the problem seems to be self-induced 
by the compiler:
