yes, i was able to reproduce it. 

actually 'xmllint --postvalid' would do the correct post parsing validation,
but this passes correct as well. i found out, that the segmentation fault
was caused by two not properly initialized struct members in the validation 
context.

XML::LibXML used the same code as xmllint did, so it was quite hard to
figure out what was going on there. It seems, that perl messes the memory 
a bit, so a variable (in this case the validation context) may gets some
values where no value should be. 

the problem goes away after initializing the particular members in the
validation context. this is now done in XML::LibXML's cvs version.
