      The BSON Python package can throw exceptions; the GDB pretty printer allows these exceptions to escape up into gdb/lldb, which can cause them to crash (I'm not sure why).

      Here is an example where I managed to get gdb to print a python stack trace and not crash (this is difficult to achieve):

      (gdb) p oplogBSON         
$13 = owned BSONObj 340 bytes @ 0x555556a614a8Traceback (most recent call last):
  File "buildscripts/gdb/mongo_printers.py", line 130, in children
