  One problem could be that the memory allocation function
obtained at compile time when referencing the address for 
free() malloc() and realloc() are functions not compatible
with the free() malloc() and realloc() function used at runtime,
this sounds screwed, but perfectly possible in an MS world
with a mix of compilers, options, DLL and others "our platform
has a shorter Time To Market" jokes...
  One possible solution could be to call xmlMemSetup(), see
    http://xmlsoft.org/xmlmem.html
from the start of the program to force the library to use the
version of free() malloc() and realloc() in use by the 
main() part of the program instead of the ones found at 
link time. Of course this call to xmlMemSetup() should be done
before xmlInitParser() since this routine does memory allocations.
