Comment 2

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Gabriele, is it correct that only the first reported crash here is relevant?

Comment 3

[Gabriele Svelto [:gsvelto]]

Yes, this behavior was changed recently to print the relevant minidump first (bug 1605328). Unfortunately it seems that we don't have symbols for standard libraries so the stack isn't great.

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Thanks Gabriele! As it looks like there is at least a libxul frame in the stack of the crashing thread:
