Crash Data

Summary: Crast at [@RtlpCoalesceFreeBlocks ] → Crash at [@RtlpCoalesceFreeBlocks ]
Just as one would expect from corrupted heap crashes, the stacks are all
over the place, with scarcely any two stacks looking similar.

So, what's MoCo's strategy for finding the culprit? 
Do we make/release a version with a special debug heap? or ?
Product: Firefox → Core
QA Contact: general → general
Version: 3.5 Branch → Trunk
That's not what I see at all.  What I see is various winsock hooks (LSPs) crashing themselves within the Firefox process.
Group: core-security
Depends on: 514612
For example, SpeedBit Video Accelerator (bug 514612).
Adobe Acrobat Reader (bug 514898)

if you pick a random crash, you'll find a random culprit. we already have complaints about some libraries (esp. avg, symantec and vlc [which should be blocklisted!]), so i'm not going to file all of them.

This just blew up. Counts of for any Firefox version. Date lags actual crash
date by a day.

seeing the dates and the high presence of avg filed could be somehow related to the new release of AVG 8.5.420, if i have found consistent dates it has been released on 24 Sep 2009 and a first update of it (8.5.420a17) has been released on 02 Oct 2009 (dunno if this release is fixing/reducing crashes), release notes are not talking about this kind of fixes.
cc-ing prazak, he could know more about eventual relations with AVG
It seems that nVidia Firewall is causing this in some cases, a user with bp-48b7e3c5-1ddb-4a36-9397-6fee82091102 on support.mozilla.com fixed the problem by removing nvlsp.dpp with Lspfix.

Not blocking at this point, but if we can get good STR we could blocklist or outreach?

FF6&7 have been working fairly well.

When I ran Internet Explorer and installed the "Download Accelerator Plus" (dap97beta.exe) Plugin from http://speedbit.com/ the Installer added 'DAP' for Firefox also. 

FF6 & 7 both seemed to work after installing the Plugin, until this morning. I fired up the Debugger to see why Firefox started and then closed (takes 20 seconds and puts nothing on screen). It seems that a tag-along Program is also installed (even if the check-box is unchecked) called "Speedbit Video Accelerator". One of it's .DLLs was were FF would bail out of execution.

I went into Windows "Add and Remove Programs" and removed the "Speedbit Video Accelerator" (and did not remove Speedbit's "DAP") and now FF will start OK.


I had to use WinDbg to find out which .DLL was being called and remove a different Program than one that I could see with Firefox's 'Plugin Management'.

If we had FF popup a Box to say what the problem was it would makes things much easier than firing up the Debugger.
Still a valid crash in 8.0 - appearing at #116. Not really a top crash anymore so removing the keyword.

Now that RtlpCoalesceFreeBlocks is in the skiplist, I close it as incomplete.
