            Bug ID: 33602
           Summary: c++ filt unable to demangle lambdas in destructors
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

#include <exception>
#include <functional>

class Impl {
  template <typename F> void ImplTemplateFunc(F&& f)
    return f();

  ~Impl() {
    ImplTemplateFunc([] {

int main() {
  Impl a;
  return 0;

Generates the mangled symbol __ZN4Impl16ImplTemplateFuncIZNS_D1EvEUlvE_EEvOT_
for the call to ImplTemplateFunc in ~Impl.

c++filt is unable to demangle it.
