             Bug #: 14611
           Summary: Clang does not emit debug info for referenced
                    constants
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: googler
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: dblaikie at gmail.com

    Classification: Unclassified


Given the program:

#include <stdio.h>

int main() {
  FILE *f = stderr;
}

GCC produces debug info including a DW_TAG_variable for "stderr", Clang does
not.

This difference in behavior breaks gdb.base/dprintf.exp in the GDB 7.5 test
suite because GCC cannot resolve "stderr" in "set dprintf-channel stderr", so
far as I can tell.
