I attach the test code, which I use for testing. Compiling the code with -O3 gives the following ICE pr51179_1.f90: In function 'tiny_find': pr51179_1.f90:3594:0: internal compiler error: in check_loop_closed_ssa_use, at tree-ssa-loop-manip.c:422 (if nobody beats me, I'll try to reduce the code and open a new pr). On a 2.5Ghz Core2Duo, I get 4.1Gflops with -O2 -ftree-vectorize.
