Bugzilla

As best I can tell, my hunch from comment 7 still holds. I used a [HookCase](https://github.com/steven-michaud/HookCase) hook library to test the patch I've just submitted, on both macOS 10.15.7 and macOS 11. It seems to fix the crashes.

Here's the hook library I used (as a patch on https://github.com/steven-michaud/HookCase/tree/v5.0.0/HookLibraryTemplate). I tested with a try build containing my patch, with symbols unstripped. (The hook library needs those symbols.)

Note that for each instance of this bug's crash that gets fixed, the crash stack for the "real" (underlying) crash will be missing symbols for at least one of the child process's modules.
