Thanks for the report, Jeff! Nice to see that someone besides me is
using this :-).
I think I see why the change in atimer.c is necessary: pgtk stores a
struct frame * as client_data in an atimer structure. That's a Lisp
object that can move during GC. Understood.
The other change in pgtkterm.c I don't understand. AFAICS, x_id_name of
the display_info structure is indeed only used as a character buffer
into which characters from Lisp strings are memcpy'd. Could you please
explain that one? (I'm macOS only, so I don't know anything about pgtk,
if that matters.)
