P3: Somewhat important Description
In the "Local Variables" view, I tried to open the subtree of the this pointer. The process froze.
I tried unsuccessfully to isolate a problematic subitem as special expression, but neither staticMetaObject nor QNetworkReply/Request/Manager nor some buttons threw any error.
I'm using gdb as debugger under windows 10 (version 7.2.0, the most modern one with mingw-w64)
By the way: How to decrement the 40-second limit for gdb answers? This would shorten my coding until the bug is found and fixed.
The relevant lines of the global debugger log were the following ones (some lines in German):
