Crash in mono_pmip #21184
Description
Steps to Reproduce
In VS Mac we use mono_pmip to symbolicate stack traces we get from objective c exceptions. The call to mono_pmip sometimes crashes. I don't have a reliable way to reproduce this in VSMac. I can make mono_pmip sometimes crash if I give it an incorrect address. If the address is correct, it seems to always work.
Current Behavior
mono_pmip crashes sometimes.
Expected Behavior
mono_pmip never crash. It should return null if the provided address is not valid.
