Crash in QWindowsKeyMapper::possibleKeys
-
I have been encountering an intermittent crash in QWindowsKeyMapper::possibleKeys and it seems like the nativeVirtualKey() in the QKeyEvent is > 255. The value I am seeing (based on a minidump) is 9827. Not entirely sure how it got into that state. Has anyone experience a similar crash before?
There is this bug report https://bugreports.qt.io/browse/QTBUG-36061 but judging from the comments, Qt doesn't appear too keen to put in a simple fix to early out if the nativeVirtualKey() causes an array out of bound.
Anyone has any thoughts as to why the virtual key would be greater than 255?

Hi and welcome to devnet,
No real thoughts about it be in any case there's a fix submitted for Qt 5 that should solve this.

Hi, mind if I ask which version of Qt 5 the fix was submitted for? I am using Qt 5.4.1 and still getting the problem. Forgot to mention this in my opening post.

No I don't :) For 5.6, it's pending integration.

Thanks. We might consider just integrating the change (a simple early out) into our 5.4.1 since upgrading Qt version is more involved.
