Here is the situation which is occuring in the particuler case(referring added testcase pr42710.cpp), while instantiating the template variable `value` it also needs the type to declare it (see at https://github.com/llvm-mirror/clang/blob/master/lib/Sema/SemaTemplateInstantiateDecl.cpp#L4590) and it sees that it is undeduced type , so it starts instantiating the initialization expression and in order to doing so it comes to at this point https://github.com/llvm-mirror/clang/blob/master/lib/CodeGen/CGDebugInfo.cpp#L1424 which iterates over all the VarDecl in record and try to generate debug info. again here template variable `value` comes , which was undeduced and fails to unwrap the type and finally assert fails.
