Nope.  But if MagiC re-implements part of GEMDOS that overlaps
with Hatari's GEMDOS HD emu, there can be issues.


You can debug the info further by checking what these show:
- "info gemdos" -> GEMDOS HD emu DTA table contents
- "info basebase" -> check contents from "Process DTA" address

PS. Another problem could be if some path was longer than:
	MAX_GEMDOS_PATH 256

But your case didn't seem like that.

-> Hatari has quite a bit of legacy code around GEMDOS HD emu
   which relies on host paths being at max MAX_GEMDOS_PATH long!

I've added TODOs about that to the code, but if I remember right,
fixing it would've required major surgery.
