           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

proposed fix for the issue

After the r167781 revision c++filt for
gcc/testsuite/g++.dg/other/first-global.C shows following demangling
information for "foo" constructor:

0000000000000029 t _GLOBAL__sub_I_foobar

and after fix was applied c++filt shows this output:
0000000000000029 t global constructors keyed to foobar
0000000000000000 t __static_initialization_and_destruction_0(int, int)
                 U foo::foo()
0000000000000000 B foobar
