actually DEBUG_MEMORY and friends do find a problem but they hide it just like
Ralfs patch and continue so I missed it in the output

I have a minimal file which makes meinproc4 crash:

<?xml version='1.0'?>
<!DOCTYPE xsl:stylesheet [
]>

this causes a syntax error on linux but on windows it still crashes in the same
place. At the crash place DEBUG_MEMORY finds a tag error: the memory block to
be freed is not marked with the correct tag (DEBUG_MEMORY adds a header with
this tag and more debug data to every malloced block) so maybe something writes
thru a wrong pointer or out of array bounds. Still valgrind on linux finds
nothing. 

Continuing later today... maybe I should regularly scan all memory blocks for
correct tags so I can find the place where it gets corrupted but that will take
a lot of time even with that minimal test file. The debug output is about 10GB

Any idea what could be different for linux and windows?
