Today's gcc bug is https://gcc.gnu.org/PR110271 where gcc itself crashed with ICE on pycryptodome package.

While the crash is not very interesting the change that caused the regression is very cool: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=43a3252c42af12

gcc is now able to detect add-with-carry patterns and generate branchless code for them. On x86 these are sub -> sbb.

Bug tracker says it's 100th bug I reported to gcc!
