The problem appears to be a latent bug that has come and gone a couple times (I saw it earlier on the gamess benchmark too). Recent mainlines compile it fine, but revision 128829 exhibits the problem. Opening a bugzilla since I haven't been able to spend as much time digging into it as I'd thought/hoped, and don't want to lose track of it. > gfortran -c -m64 -O2 -mcpu=power6x -fpeel-loops -ffast-math junk.f junk.f: In function 'setiv': junk.f:913: error: insn does not satisfy its constraints: (insn 5218 2288 4792 191 (set (reg:DF 46 14 [2631]) (reg:DF 65 lr [1528])) 335 {*movdf_hardfloat64_mfpgpr} (expr_list:REG_DEAD (reg:DF 65 lr [1528]) (nil))) junk.f:913: internal compiler error: in build_def_use, at regrename.c:766 Please submit a full bug report, with preprocessed source if appropriate.
