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?
