Unfortunatly the original reporter steve-_- is not able to build this PR at home.
Can we merge it just to provide a binary from the CI?

Can one else verify the crash?

Install: http://downloads.mixxx.org/builds/master/release/mixxx-2.3.0-alpha-pre-master-git6786-release-macintel64.dmg and check if it is crashing on startup.

If yes, run it from the command line with ./mixxx --developer and post the console output.

This PR is an attempt to fix this crash.

http://downloads.mixxx.org/builds/master/release/mixxx-2.3.0-alpha-pre-master-git6786-release-macintel64.dmg crashes (see crash report).
Unfortunately i can not test the patch in this PR, cause there is an build error, introduced in cb151a7

Thank you for Testing, and confirming the crash.

What is the issue with Unfortunately i can not test the patch in this PR, cause there is an build error, introduced in cb151a7

Do you have an idea to fix this, I can't reproduce the issue? This PR is against 2.2 so it should build anyway.

What is your
./mixxx --developer
output?

ERROR:root:Unmet dependency: invalid literal for int() with base 10: 'False'

is a python error .. https://github.com/mixxxdj/mixxx/pull/2054/files does not touch Python code ...
So I guess there must be something else wrong.

6fcfdc9 contains Python code. Consider verifying that compiler_major_version is determined correctly.

The CI build was successful.

I will disable the code path for Clang, because Clang 8.0.0 reports "4.2.1" (for GCC compatibility).
