I was only able to reproduce it by supplying configure with '--disable-cassert', i.e. when NDEBUG was defined. "Cassert" is enabled by default when compiling from ebuild so I am wondering how you hit that bug? Nevertheless, here is the patch.

If I do sudo emerge --info, CFLAGS is: CFLAGS="-march=native -O2 -fomit-frame-pointer -pipe" However, as shown in the error output, the -DNDEBUG is clearly present. Sounds like I have a bit of detective work to see how that's bleeding in.
Ok, figured it out. /etc/sudoers was clearing my user's CFLAGS, but not CXXFLAGS. So while this might be a bug in the package in that it doesn't compile with -DNDEBUG, it's also a bug in my configuration, because I didn't mean for that to be set.
patch in cvs. Thanks!
