2008308 - Ignore `core::result::unwrap_failed` in crash reporting signatures

Status: RESOLVED FIXED

(Socorro :: Signature, enhancement, P1)

Description

[Erich Gubler [:ErichDonGubler] (he/him)]

I discovered that, in some crash reports, Rust's core::result::unwrap_failed helper in its standard library is being reported as the signature frame. Unfortunately, this is a noisy frame that doesn't offer any diagnostic value, much like other unwrapping and panic internals already listed in socorro/signature/siglists/irrelevant_signature_re.txt.

Examples of some crash reports that his hampers:

I apparently had tangentially related (but unclear) link pasted into comment 1! I've edited it so that it actually points to something interesting. 😅
