(1) As I understand it the crash is presumably caused by a buffer
overrun overwriting the stack, not in the codec trying to decode a
corrupt (truncated) selection string, right? Ie, the problem leading
to a crash has been fixed here, it's not something in the codec that
is masked by giving it uncorrupt data?
Yes, it was just a mistake in my patches. The last patch in the above
is correct and doesn't lead to crashes.
I misunderstood X*Property() API as if they return the real byte
length. The API returns, however, the size of bytes in the assumption
of data witdth = 32bit (as format = 32).
(2) Now, this looks like a bug in the 64-bit X libraries to me.
What
happens if it gets fixed?
It's no implementation bug but a brain-dead API definition.
