Good stuff!

Hmm, I wonder what flags we need to use to get near that size?

I should have said fprintf(stderr....);
I put a few in and observed expected behavior.
One near the end of CalcArg:
fprintf(stderr,"calc arg value of %s\n",TmpStr);
One right at the start of WriteToFile:
fprintf(stderr,"number of args %d\n",NbArg);
What you say above sounds like a very possible optimizer/compiler
problem. Probably the distro flags haven't changed so we might
need to know the flags and the specific compiler version.
BTW, I'm FC19 but I always build my own executables.
