This is accomplished by adding (yet more) logic\nto strncmp_iw_with_mode to skip parameter lists if none is explicitly given\nby the user.\n\nHere\u0027s a simple example using gdb.linespec/cpls-ops.exp:\n\nBefore\n------\n(gdb) ptype test_op_call\ntype \u003d struct test_op_call {\n public:\n void operator()(void);\n void operator()(int);\n void operator()(long);\n void operator()\u003cint\u003e(int *);\n}\n(gdb) b test_op_call::operator()\nBreakpoint 1 at 0x400583: test_op_call::operator().
