I've got 2 customers stuck with an IE-Plugin C++ error:
R6025 - Pure virtual function call
This basically happens randomly while doing analysis with the IE Plugin, which crash Internet Explorer altogether. I suspect the IE client since this happens in 2 different applications, at 2 different sites.
The environment is WinXP, IE7, QVS9 SR2 7320.
Any one of you encountered the same issue? Any ideas.
I reported this behavior to the QlikView support during last august, the error occured because of a macro executed at document opening and a timing issue (which explains why it happens randomly). The bug was corrected in SR1, so maybe the bug was reintroduced into SR2 or maybe your error is a different one.
We encountered the exact same issue/error. I submitted a ticket to Support but because we were running a patch error and had no way of testing it in the unpatched SR2 (7320) they closed the case. The fact that you are getting this error helps us with our case to them.
We don't have any macros and we pin pointed it down to it only happens when you try to select something in a table on one of our sheets. There really is nothing special about this table chart - just that it uses stoplights but we have other that use that and this doesn't happen.
The "Pure virtual function call" error is not one specific error, but a generic one that indicates that a method on a former morphed object is called when the object it self is being destructed, and the base class does not support the call.
This error can show up in more than one place without being the same error.
This is classified as a bug that should be debugged properly by a Support Technican or anyone with knowledge on how to catch exceptions in a debugger. Report them to firstname.lastname@example.org. I know that we caught one of these little buggers just a couple of days ago in SR2.
I've had ideas on doing a blog post on debugging Qlikview, but so far the complexity and "gotcha's" that's painfully apparent in debugging software scenarios has stopped the evolution of this. But if people are interested, it might be worth putting some time into.
