After removing -fssa and a number of other options I still see the
following, which is different in that abort is hit rather than segfault:
gcc -c -O3 gslfft_pp.c -foptimize-register-move -frename-registers
-fschedule-insns2 -fschedule-insns -frerun-loop-opt
-frerun-cse-after-loop -floop-optimize -fpeephole -freduce-all-givs
-fprefetch-loop-arrays -funroll-loops
<__FUNCTION__ warnings snipped>
gslfft.c: In function `gsl_power2_fft256analysis_skip2':
gslfft.c:3445: internal compiler error: in calculate_giv_inc, at
unroll.c:1693
