built mixxx and when it loads it prints it can't find files in portage temp dir of alsa-lib. Reproducible: Always Steps to Reproduce: 1. install mixxx 2. run mixxx Actual Results: SIGSEGV with errors it can't load alsa-lib files from portage temp Expected Results: fine running app tried unmask and build media-libs/alsa-lib-1.2.10-r2 but it makes same problems as stable alsa-lib

For the segfault could you recompile media-sound/mixxx with debugging symbols and then get the backtrace with gdb? https://wiki.gentoo.org/wiki/Debugging#Installing_debugging_information_for_packages Other than that I think I've reproduced this. #0 0x00007ffff795684f in ??

in between I compiled mixxx and qtscript without LTO but gdb gave me: Thread 1 "mixxx" received signal SIGSEGV, Segmentation fault. 0x00007ffff7a54ed0 in ?? () from /usr/lib64/libQt5Script.so.5 I'll investigate more on qtscript now.

This worked clang-no-lto => gcc-no-lto; O1 in LDFLAGS dev-qt/qtscript-5.15.11::gentoo was built with the following: USE="jit scripttools -debug -test" ABI_X86="(64)" CFLAGS="-march=silvermont -maes -mtune=silvermont -O2 -pipe -fomit-frame-pointer" CXXFLAGS="-march=silvermont -maes -mtune=silvermont -O2 -pipe -fomit-frame-pointer" FEATURES="unmerge-logs pid-sandbox getbinpkg xattr network-sandbox ipc-sandbox binpkg-dostrip protect-owned usersync unknown-features-warn parallel-fetch multilib-strict sandbox binpkg-multi-instance assume-digests binpkg-logs config-protect-if-modified unmerge-orphans news strict buildpkg-live distlocks merge-sync fixlafiles preserve-libs binpkg-docompress qa-unresolved-soname-deps usersandbox ebuild-locks userpriv userfetch sfperms" LDFLAGS="-Wl,-O1,--as-needed -march=silvermont -maes -mtune=silvermont -O2 -pipe -fomit-frame-pointer"
So there are two issues then. Both with qtscript breaking with lto or clang. From the perspective of mixx this could be addressed by adding qt6 support and completely avoiding it. https://bugs.gentoo.org/915779
The solution to this is to globally disable lto for Qt5 packages. Packaging wise, it will be unwise for some time to stabilise Qt6-based packages as it will not integrate well in current desktop environments. IOW, even if mixxx supports Qt6 in some upcoming version, a Qt5-by-default version should still be used for stabilisation matters.
