This update addresses an issue where building on Fedora 42 may result in binaries that do not run correctly on earlier glibc versions, related to the use of PTHREAD_COND_INITIALIZER (swbz#32786).
This update also includes changes from the glibc's 2.41 stable release branch. Noteworthy fixes are:
<math.h> compatibility for historic Clang versionsgp optimization and IRELATIVE relocations on RISC-VPlease login to add feedback.

I forgot that Fedora 42 uses GCC 15, too. Same regression as in the rawhide update: FEDORA-2025-6616d58c7a
Yeah. We should probably have stopped the F42 gcc update going stable :( too late now.
There's a new snapshot for F43, btw - could try with that and see if the bug happened to get fixed upstream?
The problematic GCC commit has been reverted upstream and reimplemented in a completely different way. The crash is gone. We'll do a glibc rawhide sync from upstream glibc, using the new GCC snapshot soon.
There was a new GCC build 7+ days ago. If this GCC snapshot resolves the problem could we get glibc updated?
@davidlt Aren't we in the release freeze now? I suppose I could prepare a Fedora 42 update and have it wait in the queue.
Yes, we are in a freeze. All the updates marked for "stable" are pooling up as day 1 updates.
I personally interested in pulling a new glibc into Fedora/RISC-V 42 builds, which don't follow Bodhi, etc. As soon as there is NVR in Koji, I could pull it in.
