Funnily enough I've seen a similar problem with a friend of mine
cross-building for sparc on a Fedora Core 4 Linux box.

This particular problem seems to get caught by the version of glibc on
Fedora which has some malloc() checking. It detects a "double free or
corruption" and aborts. Disabling/ignoring the checks allows the build
to continue in this case.

IIRC this was building on the netbsd-2 branch.
