The testcase in PR38492 indeed works if I use: gfortran -O2 -ffast-math -funroll-loops -ftree-vectorize -march=native -fgraphite -fgraphite-identity -cpp -D__FFTSG -fno-strict-overflow test.f90 (i.e. no need for -fno-strict-aliasing) I'll give it a try on the full code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38431
