I can setup a condition of f->iconified.

So:

1. Setup GDB to break at the location you said, which (I believe) is 
src/pgtkterm.c:5507
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/pgtkterm.c#n5507
2. Setup a condition of f->iconified on the breakpoint.
3. Start Emacs PGTK and iconify it. It'll hit breakpoint. run `continue'
in GDB.
4. Deiconify it. This breakpoint won't be hit.

Feel free to ask me to provide more infomation.
