Thanks!

Almost.  There's just a leak to fix.

The previous data dir is only released if the datadir changed.

So here my_gdb_datadir leaks if the datadir _doesn't_ change.
I think you just need to move the xfree and my_data_dir=NULL
statements outside the `if', before the early return.
Anyway, okay with this leak fixed.
