[issue21251] Standard library trace module crashes with exception

[Terry J. Reedy]

Terry J. Reedy added the comment:

Third party compiled C crashers are nasty. Two suggestions:
1. Reduce the failing example to the minimum needed to fail. If you bypass all the python code in maps.py and device.py and just 'import dmraid', do you still get a crash at that point.
2. What happens if you run a minimal crasher with 3.4 or .5? I don't know if all the 3.x work on trace was backported.
