[xml] Problem In Deprecated Catalog API

[Igor Zlatkovic <igor zlatkovic com>]

Hi,

The two functions xmlCatalogGetPublic and xmlCatalogGetSystem in 
catalog.c are deprecated, true enough. But...

Both have an execution path which returns the address of the local 
variable 'result'. This address isn't valid after the relevant function 
returns. This can cause various amounts of trouble.

Will someone's legs end up broken if I remove the code from these 
functions and delegate the call to xmlCatalogResolveSystem and 
xmlCatalogResolvePublic?

Ciao,
Igor
