1352294 - Sisyphus - Bughunter - remove raw addresses from signature buckets

Status: RESOLVED FIXED

(Testing Graveyard :: Sisyphus, enhancement)

Description

[Bob Clary [:bc] (inactive)]

The use of raw addresses in signature buckets like 

mozalloc_abort | mozalloc_handle_oom | moz_xmalloc xul.dll@0xcc48ed xul.dll@0x1622aee xul.dll@0xcc2014 xul.dll@0x1622aee

Does not provide value. As in this case, this typically occurs in out of memory situations where there is not enough memory to actually create the stack using symbols and the raw address is random. This leads to the creation of distinct buckets which have no intrinsic value. By eliminating the raw addresses we can group related crashes better. For example, we would use

mozalloc_abort | mozalloc_handle_oom | moz_xmalloc xul.dll xul.dll xul.dll xul.dll

The extra xul.dll's aren't that useful but they do show the depth of the stack and I think are ok to leave in.
