1713216 - Modify Complex filter rules causing app crash without any notification or trace

Status: RESOLVED DUPLICATE of bug 1588155

(Thunderbird :: Filters, defect)

Description

[github]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

I've a filter rule with 671 conditions in it.
If you cannot easily reproduce the bug, I can post the conditions listed in the MsgFilerRules.dat file.

Some lines relative to the filter options:
type="48"
action="Mark read"
action="JunkScore"
actionValue="100"
action="Move to folder"

All conditions are in OR
The conditions are a mixed variety between "subject,contains", "subject,begins with", "subject,is", "body,contains", "from,is", "addresses,contains", "all addresses,is" and "all addresses,contains".

Actual results:

If I click on modify button, the application crashes after few seconds without any popup message box and any request to automatically report the bug that caused the crash...seems that thunderbird just kill itself for some unknown reason

Expected results:

When the conditions were 670 or less, no problems happened.
All other filters with less or just few conditions works correctly in this interested account and also on all other configured accounts
