Default Problem with AU builds on Xcode10

I am starting to move my projects to Xcode 10 (from 9.4) in preparation for OS Catalina, etc.

All of these projects compiled perfectly in Xcode 9.4 but now in Xc10 AU builds are not working.

AAX builds works perfectly in Pro Tools
VST2 and VST3 builds work perfectly in Reaper, Cubase and others

But AU builds crash all DAWs instantly and don’t get past the first step of auval - which gives “SIGBUS 10” error.

What broke here? I can’t run debugger because of instant crash upon loading the plugin in any DAW.

Any suggestions where to look appreciated!

Never mind - I found the problem. Bad array pointer in reset function (out of range). I understand from Google that's what "SIGBUS 10" error usually indicates (trying to access inaccessible memory) - and it was correct!

Interesting that AAX, VST2 and VST3 versions of this exact same code all run flawlessly completely ignoring this error. Either the AU interface has better error checking - or it is less robust, IDK.

Scratch the "never mind" above - AU builds still don't work (known good projects that worked in Xc 9.4.1).

Auval fails with

/usr/bin/auval: line 8: 1838 Bus error: 10 arch -x86_64 /usr/bin/auvaltool "$@"


What is this cryptic info indicating?
