Kewen Lin <linkw at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |msebor at gcc dot gnu.org --- Comment #13 from Kewen Lin <linkw at gcc dot gnu.org> --- Thanks again for the reduced test case and the information! I tried to bisect it but encountered some build failures on _Float32 error etc., through grepping the log I switched to start from r13-2887 (good) to r13-7206 (bad). The bisection shows the culprit commit is r13-3378-gf6c168f8c06047 which was backported to GCC-12, it seems to match the observation new gcc-12 fail while gcc-11 pass.
