  I can't reproduce this with CVS version on Linux. Even running with
valgrind, no memory access error is detected:

paphio:~/XML -> ./xmllint --noout --relaxng testcase.rng testcase1.xml
testcase1.xml validates
paphio:~/XML -> ./xmllint --noout --relaxng testcase.rng testcase2.xml
RNG validity error: file testcase2.xml line 2 element dcument
Expecting element document, got dcument
testcase2.xml fails to validate
paphio:~/XML -> valgrind  ./xmllint --noout --relaxng testcase.rng testcase2.xml==31613== Memcheck, a.k.a.

  This seems platcform/version specific, try to upgrade with the CVs version
and if you still have a problem debug it on your platform. This kind of error
is really basic I have no idea where this came from,
