Bug ID: 38189
Summary: Assertion failure after bad typo correction
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: rtr...@google.com
CC: llvm-bugs@lists.llvm.org
In the following example, the using declaration is incorrect since it refers to
a non-existent class. Clang attempts to typo-correct this, but the correction
is a function instead of a class. This later triggers an assertion.
$ cat test.cc
template <class T>
struct ptr {
ptr(T*);
};
namespace NS {
struct _First__End_ {
static ptr<_First__End_> New_SecondPart__End_();
};
} // namespace NS
using NS::_First__SecondPart__End_;
void run() {
ptr<_First__SecondPart__End_> un = _First__SecondPart__End_::NewInstance();
}
$ clang test.cc
test.cc:12:7: error: no member named '_First__SecondPart__End_' in namespace
'NS'; did you mean 'NS::_First__End_::New_SecondPart__End_'?
using NS::_First__SecondPart__End_;
