            Bug ID: 16989
           Summary: crash on invalid in end-of-tu instantiation
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: nlewycky at google.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Testcase:

class C { 
  template <class T> 
  C tpl_mem(T *) { 
    return 
  } 
  void mem(int *p) { 
    tpl_mem(p); 
  } 
}; 
class C2 { 
  void f(); 
}; 
void C2::f() {} 

The crash is an assertion here:

#5  0x0000000001685c7a in clang::TemplateDeclInstantiator::SubstFunctionType (
    this=0x7fffffffc070, D=0x5438270, Params=...)
    at SemaTemplateInstantiateDecl.cpp:2676
2676        ThisContext = cast<CXXRecordDecl>(Owner);
(gdb) p Owner
$1 = (clang::DeclContext *) 0x54386b0
(gdb) call Owner->getDeclKindName()
$2 = 0x3b09977 "CXXMethod"
(gdb) call Owner->dumpDeclContext()
class C2;
