here is another report out of the tb database... couldn't repro this one either.. http://semo.net User Comments clicked on a link to cnn to see how attacks in Jordan were foiled, http://semo.net/sendoff.asp?Name=CNN&URL=http://www.cnn.com/2001/WORLD/meast/11/18/inv.jordan.intelligence/index.html not sure what came up, but it said that netscape had performed an illegal operation & would be shut down.

-> investigating for 0.9.7
the stack traces in this bug look pretty bunk... nsSocketIS::AddRef cannot possibly invoke nsFileChannel::AddRef :(
if this is only happening on the 0.9.4 branch, then i may know what the problem is. my patch for bug 83526 included a fix for a race condition in nsHttpHandler::ProcessTransactionQ. this race condition could cause a crash, which may actually be this crash. this is the patch: http://bugzilla.mozilla.org/attachment.cgi?id=47292&action=view note that this patch is actually quite large, so we probably don't want it on the 0.9.4 branch. it may be difficult to extract the relavent portions needed to avoid the crash, but the resulting patch probably won't look that much like the one on the trunk.
s/but the resulting/so the resulting/
looking through http://ftp.mozilla.org/pub/data/crash-data/detailed-crash-analysis-all.html and it seems as though this is not happening on the trunk. so, considering that the patch for bug 83526 represents the only real difference between the relavent code on the trunk and the branch (provided of course if the stack trace can be trusted), i think we need to land some part of that patch on the 0.9.4 branch.
jan, are we seeing this 0.9.5 talkback data? darin, can you suggest some specific (if any, maybe just HTTP surfing is enough) tests for verification on the trunk here?
i have absolutely no idea how to reproduce this crash. i have never encountered it myself. also, note that the stack trace is extremely questionable... so, this is probably due to someone scrubbing memory somewhere... making this a very difficult bug to track down.
while this is a top crasher, given that 1. the patch seems to be large (and in my assessment too risky for 0.9.4) 2. our MTBF is reasonable enough, I am marking this bug as edt0.9.4- If you feel otherwise, please present counterarguments
