When trying to launch a 32 bit openGL app on Fedora with the Nvidia beta driver (open version), the app simply does not launch due to a sigsegv by the app. This happens with glxinfo32 and steam (Backtraces attached). This seems to be a bug with Fedora and not the Nvidia driver itself as the flatpak version of steam works just fine, even with the beta driver in the same Fedora install. Also reported to Nvidia though just in case This only reproduces with Fedora 42 and not 41. To reproduce, use a native (no flatpak) version of steam, 32 bit glxgears, or 32 bit glxinfo. Reproducible: Always Steps to Reproduce: 1. Install Fedora 42 with Nvidia driver from RPMFusion or negativo17 2. Launch 32 bit version of glxinfo, 32 bit glxgears, or steam. (non flatpak) 3. Will get a coredump Actual Results: Segfault with a sigsegv. Expected Results: App should launch just fine with the library https://bugzilla.rpmfusion.org/show_bug.cgi?id=7180 Has been reproduced by RPMFusion team.

Thanks for the report. However can you please report it upstream instead, https://gitlab.freedesktop.org/glvnd/libglvnd Thanks in advance and sorry such a moving target.
I am also having this problem and created an issue report as I could not find one on the libglvnd page and it has led to some very weird problems while one of the libglvnd devs has been trying to help me solve this. The issue report is here https://gitlab.freedesktop.org/glvnd/libglvnd/-/issues/252 One of their team members has done testing and it seems the problem is not with libglvnd but is in an even weirder spot.
I submitted a bug report for glibc since the problem seems to be with glibc: https://bugzilla.redhat.com/show_bug.cgi?id=2357062
It seems the problem may be with the dynamic loader and the Nvidia driver. A Glibc dev took a look and confirmed its not glibc patching the function but something else.
Fixed in nvidia 575.xx beta
