The GWP-ASan project is a debug tool written by Google for Chrome. It’s purpose is to detect certain types of memory errors (including use-after-free). Unlike regular AddressSanitizer (ASan), the GWP-ASan project does this in a more lightweight and sampled way, meaning that each allocation is only checked with a certain probability.

The overall goal of our project is to port gwp-asan to Firefox including crash reporter support and deploy it to various channels, depending on how performance works out.

Is this bug also going to be used to track crashes found with PHC, or is there a separate meta for that?

It is currently being used to track crashes, but if someone wanted to create a separate bug for that I wouldn't object.
