[Ryan VanderMeulen [:RyanVM]]

Gabriele, is it possible to figure out where symbols for these libraries might live?

Comment 2

[Jamie Nicol [:jnicol]]

Crashing threads are BrowserIcons-th, DefaultDispatch, and ThumbnailStorag, so this seems like a Fenix regression rather than a platform graphics one.

The bug is linked to a topcrash signature, which matches the following criterion:

Gabriele, is it possible to figure out where symbols for these libraries might live?

Possibly in Android system builds, but we haven't managed to scrape those yet, and I'm not even sure if the symbols are really available or the binaries are fully stripped.
