I can reproduce the segfault on x86 with -r1 and -r3.
Ok, I think I have found a solution. Will soon be in portage with 2.1.6, silently fixing in older versions.
Thanks for fixing. I'ld prefer if Gentoo upped the revision number with every bug fixed... There is one flaw left in the 2.1.5-r3-fixed-today(or was that yesterday) version: that's the basemath/buch2.c error message during compile. Both the 2.1.5-r3 and 2.1.6 version seem to work correctly.
That was a special case yesterday: Those with ~x86 would get the bump to 2.1.6, those with x86 would get the one to 2.1.5-r3. 2.1.5-r4 is out now which fixes the problem in buch2.c. Thanks for keeping your eyes open.
