At least this is something I can do at the momen. Please find them here
(i386 versions):
http://www.omnilan.de/downloads/pkg-static.core-i-avx
http://www.omnilan.de/downloads/pkg-static.core7

The former crashes on Haswell while running fine on IvyBridge, the
latter has been compiled with CPUTYPE=corei7 instead of core-i-avx and
doesn't show problems on any syste,

Thansk for your attention!!!
