Subject: When the template specialization header is missing, set a valid source location for... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d62d9015c76d4e7dee1fddd9603b92098b355e15;p=clang

When the template specialization header is missing, set a valid source location for the template keyword when recovering.

Otherwise ClassTemplateSpecializationDecl::getSourceRange() will mistakenly consider itself as an implicit partial specialization
and lead to a crash.

Fixes rdar://14063074
