1192736 - [e10s] Asking to end the task to task manager is raising an error/exception on plugin-container.exe

Status: RESOLVED INVALID

(Firefox :: General, defect)

Attachment: Error screenshot.png

So, I was able to reproduce it with 100% rate:
Open nightly with e10s enabled, open your task manager, select nightly and click on end of task. It won't wait for ant confirmation, and will close and + raise and error message about plugin-container.exe

This does not reproduce if e10s is unabled.

See the screenshot (in french) about what is it raising.
It could be translated by

"The exception Breakpoint
A breakpoint has been reached
(0x80000003) produced in the application at 0x.... place."

Maybe does plugin-container not handle some signals? I'm a bit unaware about how Windows does work about this, but Linux is having different signals, how are they handled for each of them? Can some be not handled correctly?

Just to add missing informations: this is happening on Windows 8.1.

I set the crash keyword, but as it's not a "normal" use case, maybe severity shouldn't be very high?

We're in the process of removing support for plugins (bug 1677160), so I think this bug is irrelevant now.
