  Seems you didn't cleaned up the memory used by global data in the library
after usage. Compile with memory debug, use xmllint to reproduce the bug and
check the .memdump after validating with relaxng. If the leak show up
in your code and not with xmllint, that mean your code has a bug. In that
case I bet you forgot to call xmlCleanupParser() when done using libxml2.
