--- Comment #31 from Marcel Wiesweg <marcel.wiesweg at gmx.de> ---
Git commit 767a14c626384d646276972c531e9a617e36face by Marcel Wiesweg.
Committed on 18/10/2012 at 22:18.
Pushed by mwiesweg into branch 'master'.

Prevent integer overflows when calculating the memory necessary for loading an
image.

This can happen particularly for images requiring chunks of >4GB and when using
a 32 bit
variable to store width and height. Worst case, a smaller chunk of memory was
allocated,
resulting in a crash.
FIXED-IN: 3.0.0
