https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80158 --- Comment #17 from Bill Schmidt --- The following fixes the reduced test case. Could you please test it on the full 416.gamess build? I'll regstrap it on x86-64 and ppc64le. Index: gcc/gimple-ssa-strength-reduction.c

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80158 --- Comment #16 from Bill Schmidt --- Ah, that's not it at all. This is much more subtle. This has to do with candidates that have alternate interpretations (as either a CAND_ADD or a CAND_MULT). We fix up the candidate that we replace, but

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80158 --- Comment #15 from Bill Schmidt --- This is the only spot where we don't do an in-situ replacement. Testing a patch to fix that.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80158 --- Comment #13 from Bill Schmidt --- OK, sure, that is quite possible. Seems like something that should have popped up before, but I guess the information gathered from the old cand->stmt must have been harmless.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80158 --- Comment #9 from Bill Schmidt --- Thanks, those dumps are very helpful. I found an x86 box, just need to get set up now. The SLSR dump is truncated but it still tells me what it was working on when it died, so should help me out.
