I am using "cc: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]" .. with the
following options.
cc +DD64 -Ae -D_REENTRANT +Z -c -g -DNDEBUG -O -I. -IInclude -I./Include
-DPy_BUILD_CORE -o Modules/gcmodule.o Modules/gcmodule.c
So that is +O2 level.

Interestingly the following patch fixes the bug, and shows that this is a
optimization bug in HPUX compiler:

I will try to use a different optimization level now.
