guile-1.8.8-r2 builds fine. guile-2.0.12 fails with:

Tried to reduce the used USE-flags to: regex and networking. Dropping regex fails with https://bugs.gentoo.org/show_bug.cgi?id=596322. Networking is needed for gnutls and autogen.

I have experienced the same issue on AMD64. It seems to be cause by -ffast-math being enabled in -Ofast.

Adding -fno-fast-math to my CFLAGs eliminated the issue.

I've found -O2 also can prevent compilation.

-O1 worked.

Is this still present for new versions 2.0.13-r2 and 2.0.14-r2 which are in tree?

I have done several builds on amd64 for 2.0.14-r3, my findings:

I'm unable to reproduce any issue with only -O2.

I can reproduce the failure with only -Ofast, and make it pass using -Ofast -fno-fast-math.
