Subject: [PCH] Set the DeclContext before doing any deserialization, to make sure internal
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=53a8b9789c8e87b67aa802e2df205db702c5ef27;p=clang

[PCH] Set the DeclContext before doing any deserialization, to make sure internal
calls to Decl::getASTContext() by Decl's methods will find the TranslationUnitDecl
without crashing due to a parent declaration context still deserializing.
