Thank you for coming back on this! I agree it is very odd, otherwise many people would experience it..
What I did, I have commented out:
/* set main menu */
[NSApp setMainMenu: menu];
// [pool release];
as expected it start working fine, but not sure if it leads to memory leak ..
Also If run debug in Xcode and do step by step debugging Emacs hang this call:
/* FIXME: we'd like to only parse the needed submenu, but this
was causing crashes in the _common parsing code.. need to make
sure proper initialization done.. */
/* if (submenu && strcmp ([[submenu title] UTF8String], SSDATA (string)))
submenu_start[i] = menu_items_used;
menu_items_n_panes = 0;
*hang*--> submenu_top_level_items[i] = parse_single_submenu (key, string, maps);
submenu_n_panes[i] = menu_items_n_panes;
submenu_end[i] = menu_items_used;
Anyway I am ready to troubleshoot and apply any patches/check code if needed.

Hi, thanks for reporting this. I didn’t get the previous email for
some reason, so I missed it.
This is an odd one. I don’t think it has anything to do with pthreads,
but I don’t really understand what’s going on. My best guess is that
somehow the autorelease pools are being drained out of order. I don’t
know why using tramp would cause that to happen.
One solution would be to remove the pool from ns_update_menubar
completely, but I assume it’s there for a good reason.
