626178 - Every keypress leads to ASSERTION: QueryInterface needed: 'query_result.get() == mRawPtr'

Status: RESOLVED WORKSFORME

(Core :: Widget: Win32, defect)

Description

[Philipp von Weitershausen [:philikon]]

Attachment: screenshot

This is a fresh (clobbered) debug build of https://hg.mozilla.org/mozilla-central/rev/f7ac9667229b on Windows 7. Every single keypress results in this assertion:

###!!! ASSERTION: QueryInterface needed: 'query_result.get() == mRawPtr', file c:\dev\mc-jpake\objdir-ff-debug\dist\include\nsCOMPtr.h, line 544

Doesn't happen on OSX so I'm assuming it's a Win32 widget issue. Apologies if I got the wrong component.

timeless has some instructions on how to track down which class is misheaving here in bug 541653 comment 2. Will try to check that out.

This is fallout from a) bug 581596 for creating an IID but not actually supporting QueryInterface to it b) bug 610821 for creating an nsCOMPtr to a concrete object which ends up actually trying to use the bogus IID.

Is this still a problem?

I did get this on Windows 7 but it disappeared some time ago.
