Using 4.4 I get the following:
aa.f: In function 'fftrc':
aa.f:2: error: expected an SSA_NAME object
aa.f:2: error: in statement
# NMT.31 = VDEF <NMT.31> { NMT.31 }
IMAGPART_EXPR <(*x_29(D))[1]> = 0.0;
aa.f:2: internal compiler error: verify_ssa failed
while with 4.3:
aa.f: In function 'fftrc':
aa.f:2: internal compiler error: Segmentation fault
