[libxml++] Segfault with node->find()

If I use something like:

xmlpp::NodeSet found;
const xmlpp::TextNode* node_text;
found = node->find( "./some/valid/path" );
node_text = dynamic_cast<const xmlpp::TextNode*>(found[0]);

Everything is fine.

However, this:

found = node->find( "./some/INVALID/path" );

produces a segfault.

Am I doing something wrong? gdb isn't hugely helpful because I just get
tied up in inlined template functions for vector and there's a segfault
_somewhere_ in them!

Do I need to check beforehand whether there's anything at the end of the
path?

Thanks in advance,

Rupert

I can't reproduce such a behavior. Is the segfault on find itself ? Could y=
ou=20
post a sample code on which you have the problem ?

And about gdb, try to obtain the backtrace.
