Bug reference: 18943
Logged by: Karavaev Alexey
Email address: maralist86@mail.ru
PostgreSQL version: 17.5
Operating system: alt workstation 10.4 x86_64
Description:
Return value of a function 'xmlBufferCreate' is dereferenced at xpath.c:177
without checking for NULL, but it is usually checked for this function.
The function 'xmlBufferCreate' may return NULL, and in some cases the code
xmlStrdup(buf->content) will throw an error.
