--- Comment #3 from Mikael Pettersson <mikpelinux at gmail dot com> --- git bisect identified the following as the start of this error: # new: [04c9cf5c786b94fbe3f6f21f06cae73a7575ff7a] Implement new RTL optimizations pass: fold-mem-offsets Note the error still reproduced as of 2024-01-07 so wasn't fixed by PR111601. (Technically my bisect has one more commit to test, the one immediately before the above, but that one only updates gcc/d/ so cannot have any impact to my bootstraps.)
