Fixed since GCC 4.2. I don't know by what though.

[Bug c/25755] New: ICE in testsuite/gcc.c-torture/execute/20050316-1.c

I'm getting an ICE in current 4.1 branch on Solaris 10 x86.  It's trying to
compile testsuite/gcc.c-torture/execute/20050316-1.c and getting:

------- Comment #1 from brett dot albertson at stratech dot com  2006-01-12 17:48 -------
Update:  If I add "-mmmx" as a command line argument, this successfully
compiles for me.  I got the idea from this error message:

dev-zero:{root}# /opt/gcc-4.1/bin/g++ -c 20050316-1.c
20050316-1.c: In function 'int test2(int __vector__)':
20050316-1.c:17: warning: MMX vector argument without MMX enabled changes the
ABI

BTW, trunk is still seeing this ICE.
