Crash Data

This bug was filed from the Socorro interface and is 
report bp-0cd57600-a666-4323-9c24-f4c2d0170714.
=============================================================

This started in Nightly 20170714030205 and has been happening since. It's happened 40 times across 35 installations.

The stack trace makes it look like there's some refcounting problem in the HttpBaseChannel destructor. Maybe there is some memory corruption, or premature free, or something like that?

Likely regression range is here:

Honza, you have a few changes in that range. Could any of them have caused this?

I'd more bet it was happening between bug 1377004 and bug 1377004.  Dragana?

Dragana, this is the #4 Windows topcrash in Nightly 20170721030204. Do you have a diagnosis, or do you know which patch caused the crash?

yes.
It is TFO. there is a pref to turn it off. I am trying to figure out why it is crashing therefore the TFO is on... I will turn it off before it goes to beta.

This is the #3 and #9 Windows topcrash in Nightly 20170731100325 and 20170731175927. No new crashes after 7/31 so it looks like turning TFO off does stop the crash.
