I am suspecting the first one. Jakub has a fix which he is I suspect will be submitting tomorrow too. Thanks, Andrew Pinski Hi, Thanks for these pointers. I tried to narrow a bit more today these regressions today. Most of them seems to have been introduced with the fixes for GCC bug 107569 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107569 ). However all the iseqsig tests seems to fail because of another reason, it was already failing with the gcc master branch of 15th of October, and I couldn’t test earlier commits as I had build failures. I have found GCC bug 106805 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106805 ) which might be related. Cheers, Romain
