Comment 5

[Henrik Skupin [:whimboo][⌚️UTC+2]]

The minidump files are only a couple of bytes in size. So I assume we somehow fail to write it to disk when Firefox crashed. Gabriele, do you have an idea?

Comment 6

[Gabriele Svelto [:gsvelto]]

This is very odd, the minidump is present and contains minidump-ish data... but is missing the header entirely. The first 128 bytes are filled with zeros, that's where the header and directory should be.

Comment 7

[Henrik Skupin [:whimboo][⌚️UTC+2]]

For all the failures seen so far these are all on MacOS.

Shall I file a bug for the crash reporter? Or is there not enough information to act on?

Comment 8

[Gabriele Svelto [:gsvelto]]

I've opened a bunch of minidumps and they all exhibit the same issue so yeah, let's open a bug.

Comment 9

[Henrik Skupin [:whimboo][⌚️UTC+2]]

This is bug 1614931 now. Thanks!
