            Bug ID: 16874
           Summary: Can't break on function in anonymous namespace
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: critical
          Priority: P2
         Component: c++
          Assignee: unassigned at sourceware dot org
          Reporter: rguenth at gcc dot gnu.org

namespace { int foo (void) { return 0; } } int main() { return foo (); }

> gdb ./a.out

so it doesn't work, not from toplevel context before starting the program
nor from a context within the TU that contains the anonymous namespace.

Breaks debugging of GCC big times - try to break on
cfgexpand.c:pass_expand::execute - we want to be able to do that from a
context that is not necessarily local to that TU.
