bug#23462: 25.0.93; Crash on OS X when suspending main frame

[Anders Lindgren]

Hi!

 

Right, on a hunch that it's something to do with Emacs receiving and
processing signals or input of some sort during or immediately after
minimization, I tried wrapping

    [[view window] miniaturize: NSApp];

in x_iconify_frame with block_input and unblock_input:

    block_input();
    [[view window] miniaturize: NSApp];
    unblock_input();

which seems to have solved the crash.

This seems like a much cleaner solution than the earlier.

It looks very similar to the startup crash I tracked down a fixed about a year ago, when input events started to arrive before emacs had finished its initialization.
