I just tried to compile the package scsires-0.7-4.7 with the GNU
C compiler version 4.5 snapshot 20100128 and the compiler said

scsires.c: In function 'scsires_issue_reservation':
scsires.c:911:1: error: type mismatch in shift expression
vector unsigned int
vector <unnamed type>
int
vect_var_.289_442 = vect_perm_odd.250_390 >> 16;

then

scsires.c:911:1: internal compiler error: verify_stmts failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O3 required.
It compiles fine with -O2.
