[xml] [BUG] xmlschemas.c - segmentation fault

[Bertrand Fritsch <bfr 4js com>]

Hello,

libxml2 2.6.26

It seems that there is a bug in the xmlschemas.c file. The function 
xmlSchemaClearValidCtxt clears a xmlSchemaValidCtxt object without 
setting the nbIdcNodes member to 0. When the context is used a second 
time, some IDC nodes are cleared twice.

Attached is a proposed patch.

Regards,
Bertrand.
