Code running in 5.12, but not in 5.15 or higher
-
Hello
I generate code in Qt Creator 4.14.2
My code did run in all older Versions up to 5.12.4
But when I use it in 5.15.2 or 6.0.1, it does compile but crashes with the following message:--------------------------- Signal erhalten --------------------------- <p>Der Prozess wurde wegen eines Signals vom Betriebssystem angehalten.<p><table><tr><td>Name des Signals : </td><td>SIGSEGV</td></tr><tr><td>Bedeutung : </td><td>Segmentation fault</td></tr></table> --------------------------- OK ---------------------------It crashes in the line
ui->setupUi(this);In mainwindow.cpp
What can i do to avoid this?Thanks,
Thomas

Please post the stack trace after crash.
Also, did you completely rebuild your project after switching to other Qt version?

Is this the stack trace?

Simplify your code until it no longer crashes. Doesn't look to hard to track down the issues since it's directly in the ctor. I would guess 'ui' is not initialized but without code it's just a wild guess.
