In CLion, there should be a way to get the "MI traces" or something like that,
the log of the communication between CLion and GDB.  I've never used CLion, so
I can't really help you there.  But if you can get that, it would be helpful to
reproduce the problem.  It will allow replaying the same steps, but without
CLion.

Since the bug happens while expanding a symtab, pPerhaps something that could
reproduce the problem:

1. Load your binary in GDB
2. Use the command "maintenance expand-symtabs".
