Nope. From FreeBSD's dmesg:
CPU: AMD Athlon(tm) Processor (1208.75-MHz 686-class CPU)
Origin = "AuthenticAMD" Id = 0x642 Stepping = 2
Features=0x183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR>
AMD Features=0xc0440800<SYSCALL,<b18>,MMX+,3DNow!+,3DNow!>
SSE2 isn't one of the listed features.

What instructions is causing the crash?
Are you testing on a machine which has SSE2 ?

There is the issue, the testcase should be not run on your computer as it is
using SSE2. So this is a testsuite issue.

Please look at gcc.dg/vect/ how this should be done. There is a check_vect ()
call before each runtime test (check_vect is in tree-vect.h). I think that
fortran vectorizer tests should call this test too - perhaps via C bindings?

Isn't this a dup of 34168?
