PR11926 + duplicates: Fix crash in -Wuninitialized when using a compiler like
g++4.7, which reuses stack space allocated for temporaries. CFGElement::getAs
returns a suitably-cast version of 'this'. Patch by Markus Trippelsdorf!

No test: this code has the same observable behavior as the old code when built
with most compilers, and the tests were already failing when built with a
compiler for which this produced a broken binary.

12 years agoRecursiveASTVisitor: Visit instantiations of member templates of class
Richard Smith [Tue, 24 Apr 2012 20:39:49 +0000 (20:39 +0000)]
RecursiveASTVisitor: Visit instantiations of member templates of class
templates. In an implicit instantiation of a member class, any member
templates don't get instantiated, so the existing check which only visited
the instantiations of a defined template skipped these templates'
instantiations.

Since there is only a single declaration of a member template of a class
template specialization, just use that to determine whether to visit the
instantiations. This introduces a slight inconsistency in that we will
visit the instantiations of such templates whether or not they are
defined, but we never visit a declared-but-not-defined instantiation, so
this turns out to not matter.
