Not sure if this is fixed. Just ran across it today. Note: There should be a Platforms component for reporting purposes. This would fall under "Platforms:Windows".
---------------------------------------------------------------
In QWindowsKeyMapper::updatePossibleKeyCodes, an array of virtual keys is used with bounds of 256. The passed in virtual key is used as an index into this array. However, if you generate an extended key, by pressing Alt and numeric keyboard, the resulting virtual key is too large. In my case 9830 which is way over the array boundaries.
Offending Code:
// Fills keyLayout for that vk_key. Values are all characters one can type using that key
// (in connection with every combination of modifiers) and whether these "characters" are
// dead keys.
void QWindowsKeyMapper::updatePossibleKeyCodes(unsigned char *kbdBuffer, quint32 scancode,
quint32 vk_key)
{
-> if (!vk_key || (keyLayout[vk_key].exists && !keyLayout[vk_key].dirty))
