Multithreaded app crashes under OpenBSD if Form1.Show called via signal
«
on:
November 17, 2020, 11:41:11 pm »
The very same GUI app (
http://oscomp.hu/depot/lazarus_openbsd_signaltest.zip
) as in the
other topic
have another issue with threads and signals under OpenBSD.
The program can be signalled with
SIGUSR1
which will call
Form1.Show
. However, if the threads are present, then instead of popping the window up, the app just crashes. Here is the error log:
http://oscomp.hu/depot/lazarus_openbsd_signaltest_form_show.log
The setup is the same: OpenBSD 6.8 AMD64, FreePascal 3.2.0 and Lazarus 2.0.10-2.
As in the other case, this works flawlessly under Linux, FreeBSD and Solaris.
Any help is appreciated.
To quickly install Lazarus under OpenBSD, you can use my install script:
http://oscomp.hu/depot/install_lazarus_openbsd.sh
Usage:
install_lazarus_openbsd.sh x86_64 3.2.0 2.0.10 2

Jonas Maebe pointed out in the other topic, that no signal shall mess with the program's controlling subroutines, so this is solved and the solution is in the other topic.
