Hi, it's somewhat like an odyysee to submit a bug ... here it is:

compiling the same code with ot without "-march=pentium" (or "-mcpu=pentium4",
that doesn't matter) it results in:

If necessary, it's public available package, called genehunter (gh), I used
gh-v2.1_r4.tar.gz (http://www.fhcrc.org/labs/kruglyak/Downloads)

I'm not the developer, I just have to use it ;)
Please let me now if anything else is needed ...
