#96 Crash on 340mb binary compare

[olbo]

Crashes when comparing two 340mb binary files.

KDiff3 Version 0.9.92
(Saw it first in 0.9.91 then installed 0.9.92)
Windows XP Professional SP2

If i open kdiff3 in windbg i get 40106 lines of the first message:

When i ran comp on the 340mb files they turned out to be identical.
If i specify a small file first and then the 340mb files it seems to load the small file and then when it says loading B after a moment it crashes.
With some more testing on identical binary files i got some hangs, some crashes.
On two identical 104mb files it worked, i don't know if it's size related but it seems to work on all small files.
I still got the "QWindowsLocalDecoder: exceeded max internal buffer size" debug message when it worked so i guess thats not related.
