I have a problem since upgrading from openssl to version 1.1.1a.
I'm working on graphics/QGIS 3 and at startup I have a crash with this error.
Thread 1 received signal SIGSEGV. Segmentation fault.
I suspect that the module calling openssl is qca-qt5 with the openssl plugins.
This works very well with version 184.108.40.206 (svn rev 340700 for example)
I tried again on other machines without reproducing the problem. I think there was an error in the update on my test machine.
