[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2007-05-28 12:28 -------
Confirmed.  Another mangling problem:

Program received signal SIGSEGV, Segmentation fault.
0x0827e9b8 in write_expression (expr=0xb7cdd870)
    at /home/richard/src/trunk2/gcc/cp/mangle.c:2175
warning: Source file is more recent than executable.
2175          write_string (operator_name_info[(int) code].mangled_name);
(gdb) print operator_name_info[(int) code]
$1 = {identifier = 0x0, name = 0x0, mangled_name = 0x0, arity = 0}
(gdb) print code
$2 = 214
