 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
