  There is no known memory leak bug in libxml2/libxslt.

  Drop your wrappers, use mine. Recompile both libxml and libxslt
with memory debug, you will log every single allocation made by them.
This will allow you to also distinguish allocations done by the libraries
from yours, and hence see who leacks memory precisely.
  Read and follow the instructions:
    http://xmlsoft.org/xmlmem.html#Debugging

  Other than that I can't help you, but if you can expose a
bug with xsltproc, I will fix it.
