            Bug ID: 17920
           Summary: goto label at end of function fails to compile...
           Product: clang
           Version: 3.3
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: sean at chittenden.org

It appears like the grammar parser is expecting a statement after a goto label.

% clang++ -std=c++11 -stdlib=libc++ -Wall -pedantic -Werror foo2.cpp
foo2.cpp:4:1: error: expected statement
1 error generated.
% cat foo2.cpp
int main() {
  goto end;

Changing main() to include a return or even the noop "(void)0;" after the label
"end:" fixes the compilation.
