...s-opengl-120902-1 from http://wine.dataparty.no/). I get different results with all of them. Could anyone do a walkthrough with me using any of the above versions? Sometimes it seems like there is just a registry problem, other times it seems like a problem in the code. Tony -- Anthony Joseph Seward <anthony.seward@ieee.org>

...detect uses of uninitialized memory (the major feature of Valgrind/Memcheck not covered by AddressSanitizer). It will also find use-after-destruction-but-before-free in C++. The algorithm of the tool is similar to that of Memcheck ( http://static.usenix.org/event/usenix05/tech/general/full_papers/seward/seward.pdf ). We associate a few shadow bits with every byte of the application memory, poison the shadow of the malloc-ed or alloca-ed memory, load the shadow bits on every memory read, propagate the shadow bits through some of the arithmetic instruction (including MOV), store the shadow bits on e...

I haven't seen one. Sirish is going to send a patch to Julian Seward and try to get the change in a new release of bzip2, and from there we may need to ask the AOSP folks to update bzip2. AOSP has the last released bzip2 from Sept 2010. For SPEC benchmarketing, doing the right thing wouldn't help. Maybe we should put this idiom and others under a -fspec flag ;...
