Comment 1 Harald Sitter 2024-04-18 09:22:19 UTC 
The relevant line

    m_proc->deleteLater();

I am not sure how m_proc can be 0x0 though. It's where this signal originates 🤷

Git commit 8f4a57a6626d6fbc801a049d9ddcab5ff81b98b2 by Harald Sitter.

backtracegenerator: don't crash when the debugger crashes

when the debugger crashes slotOnErrorOccurred runs before
slotProcessExited and causes the latter to trip over the
since-nullpointered members. instead guard the delete operations against
nullptrs. this is done in both functions to increase reliablity even
though technically it's only needed in slotProcessExited
