MRXS 2.2 - test failures

[Agelos Pappas]

Hi,

I have written the necessary code to process MRXS 2.2 files and also 
performed cross compilation to produce windows binaries. Initially the 
changes seemed to work fine, but after further testing I encountered 
corrupted images. I was unable to identify the part of the code that 
caused the corruption, so far. Furthermore I couldn't even define the 
required steps to reproduce the problem. Therefore I went on to try the 
provided tests using valgrind. I ran the mirax related tests and I got 
lots of:

==12130== Conditional jump or move depends on uninitialised value(s)
==12130==    at 0x46EA946: ??? (in 
/usr/lib/i386-linux-gnu/libpixman-1.so.0.24.4)
==12130==    by 0x7542817: ???

Then I reverted my code back to OpenSlide's master repository (not my 
fork), recompiled and ran the tests again. I still got the same errors.
My question therefore is, does the current GitHub version of OpenSlide 
pass the provided mirax test cases, as far as valgrind is concerned? In 
my system it looks like it does not.
I am running Ubuntu 12.04 LTS 32-bit in VMWare.
