``` <jemalloc>: /var/tmp/portage/dev-libs/jemalloc-5.3.0-r1/work/jemalloc-5.3.0/include/jemalloc/internal/atomic_gcc_atomic.h:31: Unreachable code reached /var/tmp/portage/dev-util/ruff-0.8.4/temp/environment: line 2497: 4264 Aborted ${releasedir}/ruff generate-shell-completion bash > ruff-completion.bash ``` jemalloc miscompiled? ago, does jemalloc pass its testsuite for you?
I get some jemalloc test failures with GCC 15, but -fno-malloc-dce fixes those. https://github.com/jemalloc/jemalloc/pull/2704 would fix that, I think. But I think this is unrelated to the issue you've hit.
I assume you reached https://github.com/jemalloc/jemalloc/blob/17881ebbfd76529904e826f425f3266834cf3a75/include/jemalloc/internal/atomic_gcc_atomic.h#L33 ..?
With USE=debug on jemalloc, I get this in the testsuite, yay: ``` === test/integration/aligned_alloc === <jemalloc>: /var/tmp/portage/dev-libs/jemalloc-5.3.0-r1/work/jemalloc-5.3.0/include/jemalloc/internal/atomic_gcc_atomic.h:31: Unreachable code reached Aborted (core dumped) Test harness error: test/integration/aligned_alloc w/ MALLOC_CONF="" Use prefix to debug, e.g. JEMALLOC_TEST_PREFIX="gdb --args" sh test/test.sh test/integration/aligned_alloc make: *** [Makefile:683: check_integration] Error 1 make: *** Waiting for unfinished jobs.... ```
It only happens with GCC 15, it happens even with -fno-malloc-dce, and -std=gnu17 doesn't help either (wasn't sure if something was getting confused by the ATOMIC_VAR_INIT removal somehow).

OK, I think it's the same as the other ipa-cp issues (https://gcc.gnu.org/PR118138).

*** Bug 948223 has been marked as a duplicate of this bug. ***
Reopening given bug 948223. There's some ipa-cp bugs lurking still: * https://gcc.gnu.org/PR118097 * https://gcc.gnu.org/PR118535 I'm unlikely to spend time reducing jemalloc until those are fixed.
I can't seem to reproduce this anymore but ago hit it in a dupe (bug 948223) with 15.0.0_pre20250112-r2 and nothing has changed in ipa-cp.
Maybe jakub's r15-6566-g804e9d55d9e54c but I'd been testing with -fno-malloc-dce to avoid unrelated failures anyway.
OK, I've spent a while on this now, and I'm pretty sure it's fixed. ago, did you have a jemalloc binpkg in use perhaps for bug 948223?
