18117 - [Tree]Repeatedly clicking on XUL Tree items crashes Apprunner.exe

Status: RESOLVED WORKSFORME

(Core :: XUL, defect, P3)

Description

[jeffrey]

I have implemented a Tree in a dialog.  If I repeatedly click on tree cells,
I eventually get an Apprunner.exe crash that kicks me back out to the NT command
prompt that started Apprunner and I see the following:

runtime error R6025
- pure virtual function call

This is not an occasional occurance.  It happens every time. Dialog code is
below. Please contact me if you need more info, i.e., the RDF file, etc.

Marking [Tree]

Comment 3

[selmer (gone)]

Assigning to Alec, I will duplicate on current build if possible.  Setting to
M12 until we know what's causing the crash.

Comment 4

[Alec Flett]

selmer - any luck duplicating? I haven't seen this at all.... jeffrey - could
you have possibly been scrolling before this clicking? the scrollbar was pretty
screwed up until the last day or two.

Comment 5

[selmer (gone)]

Gak!  I forgot to try to duplicate this because I was so engrossed in the other
bugs.  I'd like to stay on my current track for a bit yet, maybe I can try this
Thr or Fri.

Comment 6

Updating QA Contact.

Comment 7

[jeffrey]

Alec, Jan, et al, I reproduced this again this morning after getting a note from
Jan asking if I had scrolled before the crash occurred.  Yes, the crash happens
after scrolling this tree.

[Alec Flett]

Thanks for the updates, Steve and Jeffrey....

Attachment: Possible alternate occurance of this bug

Comment 11

[selmer (gone)]

previous attachment generated by opening newsgroup window and clicking on first
message numerous times.  The crash didn't happen until I closed the newsgroup
window though...

Comment 12

[selmer (gone)]

Jeffrey claims he can't dup this anymore.  I'll file a different bug for the
crash I attached earlier.

Comment 13
