AdblockPlus for IE crashing

Reported by: -Px- Assignee:
Priority: P3 Milestone:
Module: Libadblockplus Keywords: ie_devbuild_1.2, crash
Cc: mapx Blocked By:
Blocking: Platform: Internet Explorer
Ready: no Confidential: no
Tester: Verified working: no
Review URL(s):



Windows 7 x64 SP1
Internet Explorer 10, all updates installed
Adblock Plus for IE 1.1
Default filters list

How to reproduce

No solid steps, this happens from time to time during daily browsing

Observed behaviour

Suddenly AdblockPlusEngine.exe is crashing with ExceptionCode: c0000005 (Access violation)

Expected behaviour

No crash

Additional data

I have windbg installed as default debugger, but as there is no debug symbols for Adblock available it's output not very meaningful, but I'm providing it anyway:

Additional question

I can make process memory dump with procdump next time it will happen and send it privately (as this happen on my work machine, it may contain sensitive information), if this helps to investigate the issue.

This crash is not random for me: I can reproduce it consistently & immediately on major web portals like Yahoo & MSN. If you want any technical data, just ask for it.
