Re: [libxml++] external entities substitution - libxml++ crashes

[Christophe de V. <cde...@al...>]

Hi,

I could reproduce the problem by just setting substitute_entities to true.
 From what I can see, the problem does not come from how you use the 
library.

libxml++ use the _private field of xmlNode to store pointers to children 
of xmlpp::Node.
When activating entities substitution, libxml2 seems not to keep 
_private value consistent enough for libxml++, leading to objects 
deleted twice (which cause the segmentation fault you had).

I'll try to produce a small pure libxml2 sample which shows the problem, 
do we can discuss (and hopefully solve) it on the libxml mailing-list.

Regards,

Christophe
