--- Comment #4 from Franz Sirl <sirl at gcc dot gnu.org> --- The testcode started to fail with the backwards jump threader rewrite in r12-2591-g2e96b5f14e4025691b57d2301d71aa6092ed44bc and a simple -Warray-bounds. This is proven by the fact that compiling the testcase with gcc@r12-2591 with an additional --param=threader-mode=legacy makes the warning go away. So this bug maybe a duplicate of the other bugs (couldn't find a metabug) related to r12-2591. PS: It seems I wrongly added this comment to PR 110458 before :-(.
