--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
BTW: same results for gcc-5.1.0 with isl-0.12.2:

gcc -floop-block -O2 pr63602.c
gcc -floop-interchange -O2 pr63602.c
gcc -floop-parallelize-all -O2 pr63602.c
gcc -floop-strip-mine -O2 pr63602.c

even worse:

gcc -floop-unroll-and-jam -O2 pr63602.c
../../gcc-5.1.0/isl/isl_ctx.c:172: isl_ctx freed, but some objects still
reference it
pr63602.c: In function 'main':
pr63602.c:7:1: internal compiler error: Aborted
 main(void)
