Open the fuzz testcase from bug 1861999 (https://bugzilla.mozilla.org/attachment.cgi?id=9361024)

AR: Crash
https://crash-stats.mozilla.org/report/index/d2db56d5-1e06-4d42-99dd-d22e00240727

The signature looks to be too long and doesnt fit into the signature field. Therefore the end of the signature trails off with "...."

We should probably be ignoring at least part of those frames. Moving this bug to the right component.

Component: Crash Reporting → Signature
Product: Toolkit → Socorro

Truncation is one of the steps in signature generation so signatures don't get so long they break other systems.

I can't tell what this bug is about. Is there some problem with truncated signatures in the fuzzing system?

I got this crash signature from the fuzz test. The signature was too long which I hadnt seen before so thought it may be a bug.

This is intended behavior. It gets truncated as a last step in signature generation:
