Description

Fix endless recursion in setSpecializedFrom

This could be triggered by having the exactly same specialization occur
twice in a single file. setSpecializedFrom would end up calling itself
with the same TemplateDeclaration over and over again.

Adding another recursion counter in the same way that other places already
have one fixes the problem. Unfortunately I wasn't able to generate a test
that exhibits the recursion problem.

BUG: 318492

Avoid endless recursions in TemplateDeclaration::setSpecializedFrom

Having two template specializations with the same signature causes an
endless recursion here. I don't see a reason why a TemplateDeclaration
should update its 'specializedFrom' stuff if that already is up-to-date.
So in the case the other->specializedFrom.data() is already what this
declaration has, there's simply nothing to do.


This addresses bug 318492.
