Hi David,

It's gcc from RHEL 6.5 gcc-4.4.7-4.el6.ppc64, the flags are "-DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes" vs. "-DNDEBUG -g -fwrapv -O1 -Wall -Wstrict-prototypes".

The problem is, I can't isolate it. We honestly tried it with Victor, but gcc doesn't want to miscompile a trivial example.

You can see in the attachment as far as I could get: I wrapped the macro in a function, so that it doesn't inline and compared the assembly of the good and bad object files.

Hope that helps!
