  Could not. My wrappers use special memory pool, and I NEED to use
  them.

   No problems in distinguish for me -- I don't use my wrappers for my
   allocations, I'm passing them to libxml2 via xmlMemSetup().
   And I belive, my allocation wrappers works PROPERLY, because they
   passed all test for all libc implementations, which I found and
   works for me in many huge and complex programs.

  I'll try...

  I'll try, but I think xsltproc is TOO simple to reproduce this :(
