From: "tstellar at redhat dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/108994] [13 Regression] LLVM JIT segfaults in libgcc after upgrading from gcc 12.2.1 to 13.0.1 since r13-2706-g6e80a1d164d1f9 Date: Tue, 14 Mar 2023 05:41:42 +0000 [thread overview] Message-ID: <bug-108994-4-XXp4pHwwVg@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-108994-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108994 --- Comment #17 from Tom Stellard <tstellar at redhat dot com> --- It looks like the issue is that the function classify_object_over_fdes() expects there to be a zero-length fde at the end of the fde array. It doesn't find one so it runs over the end of the array and segfaults. I don't know if this assumption is wrong or if LLVM should be emitting a zero-length fde at the end of the array.
