So we're at a point where the F33 FTBFS issues related to LTO

have been resolved (by opting the package out of LTO). I still expect
some LTO issues will pop up as packages fix things like missing
dependencies, cmake macros, etc. I continue to be available to investigate
potential LTO issues, but package maintainers will need to contact me as
I'm not actively looking for new LTO issues.
My focus is now turning to the packages with LTO opt-outs. I'll be
bug reports for upstream (primarily GCC), trying simple
workarounds for old style symbol versioning, identifying backports
upstream GCC that allow us to remove LTO opt-outs and the like. So there
should be a trickle of opt-outs removed, but otherwise should largely be
invisible to the F33 release process.
I'd like to thank everyone involved for being patient while we worked
various issues and I look forward to continuing to make
incremental improvements now that the bulk of the LTO work has
I have an issue with both Clementine and Strawberry (a fork of Clementine)
in F33 and above, users reported that disabling LTO fixes the problem.
The package builds but segfaults with:
Thread 1 "clementine" received signal SIGSEGV, Segmentation fault.

So right at the beginning of the main function and call to QtSingleApplication.
Qtsingleapplication is old code, not touched in 8 years.
Any ideas as to why LTO won't work with these packages?
