All the other uses in gdb.exp of pattern foo/default_foo have an implementation: ... proc foo {} { [default_foo] } ... but gdb_init is much more than that. Why is that different? The code introducing default_gdb_init mentions that gdb_init can be overridden. If so, then the unknown override won't be active. Or should all gdb_init overrides copy this code? Thanks, - Tom
