Crash with this pre-release that doesn't happen with official version 5.984 (prior to this pre-release cycle). I didn't try Reaper5984+dev1015_linux_x86_64, so I don't know if that also has this issue.


-Open Reaper and play a WAV file in the project (using WAV file at same sample rate of project, no resampling is happening).
-Stop playback.
-Minimize window or just make another window focused (browser, notepad, terminal, etc.)
-Click on Reaper window again to bring it into focus. Crash to desktop happens.

Output of GDB:

$ gdb reaper -ex 'set pagination off' -ex run -ex bt -ex quit

	Inferior 1 [process 9037] will be killed.

Quit anyway? (y or n) y
(The segmentation fault line happens right after switching back to Reaper.)

I tried this in Xubuntu versions 19.10 beta as well as 19.04 (both with lowlatency kernel), on two different systems with different CPU/audio hardware/mainboard/RAM (etc.) Both systems don't crash when using 5.984, but do when using this pre-release.

I also removed everything from the userplugins folder (ReaPack, SWS, etc.) just in case before doing that crash report above.

If there's anything else you'd like me to test, let me know.
