[Development] Programs crashing left and right in the CI

to summarize for Windows:

- Crashes have been observed over time in various tests, mostly in 
QtCore (QDir,QFile, QProcess see fex 

- It only affects 64bit (!) (correct me if you have observed otherwise)

- It never has been observed for MinGW (most likely since we don't have 
64bit MinGW builds?)

I think the QTest::toString appearing is an artifact of the code that 
walks the stack.

We know that it seems to depends on some obscure CI parameters (load?), 
so far, we have not been able to see anything useful in the stack traces.
