I'm experimentally rebuilding rawhide with the not-yet-released GCC 15 to see if anything breaks, and to help write the porting guide. See https://fedoraproject.org/wiki/User:Dmalcolm/gcc-15 My test build with GCC 15 failed: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed/build/8476127/ whereas my test build with GCC 14 succeeded: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed.checker/build/8477871/ Looking at the failure logs e.g. https://download.copr.fedorainfracloud.org/results/dmalcolm/gcc-15-smoketest-3.failed/fedora-rawhide-x86_64/08476127-bison/builder-live.log.gz I see: (...snippped...) 763: Leaked lookahead after nondeterministic parse syntax error: glr.cc ok 764: Leaked lookahead after nondeterministic parse syntax error: glr2.cc FAILED (glr-regression.at:1862) 765: Uninitialized location when reporting ambiguity: glr.c api.pure ok (...snippped...) ## ------------- ## ## Test results. ## ## ------------- ## ERROR: 696 tests were run, 1 failed unexpectedly. i.e. test 764 is failing for some reason with GCC 15: glr2.cc FAILED (glr-regression.at:1862) I'm investigating... Reproducible: Didn't try
glr2.cc seems to be here, fwiw: https://git.savannah.gnu.org/cgit/bison.git/tree/data/skeletons/glr2.cc
This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle. Changing version to 42.

bison has FTBFS in F42+ since January; please fix ASAP.
Dear Maintainer, your package has an open Fails To Build From Source bug for Fedora 42. Action is required from you. If you can fix your package to build, perform a build in koji, and either create an update in bodhi, or close this bug without creating an update, if updating is not appropriate [1]. If you are working on a fix, set the status to ASSIGNED to acknowledge this. If you have already fixed this issue, please close this Bugzilla report. Following the policy for such packages [2], your package will be orphaned if this bug remains in NEW state more than 8 weeks (not sooner than 2025-03-05). A week before the mass branching of Fedora 43 according to the schedule [3], any packages not successfully rebuilt at least on Fedora 41 will be retired regardless of the status of this bug.
