Qt Creator 12.0.1
Description
There are a few reports that initiating a remote debug session can cause crash of either Qt Creator itself or GDB. It is usually Qt Creator being unresponsive/frozen for a few times, then either Qt Creator itself crashes, or GDB crashes (then remote debug session of course fails to start but Qt Creator keeps working). It happens to Qt Creator 12 but not to 11. It seems to be a performance regression. Also, manually starting and attaching GDB server on target is all good. So the problem seems to be on Qt Creator side,
Attached is a piece of log that original reporter collected. Until GDB fails to start at the end, everything looks fine.
What original reporter has: i7-1065G7 + 16GB RAM. It should be more than enough for Qt Creator TBH. What I have is Ryzen 6650U + 16GB RAM, but never 100% reproduced the problem (freezing and unresponsive, yes, but no crash). What I guess is that if I do anything (clicking on unresponsive QtC window, etc..) instead of leaving QtC alone, it may crash.
