Emacs 23.2 for Mac installed from MacPorts dies on startup

Emacs 23.2 for Mac installed from MacPorts dies on startup

[John Wiegley]

I did a "port selfupdate" today to find that 23.2 was available.  So I did what I did for 23.1:

port edit emacs-app

edit the Portfile to add these lines (better optimization on OS X):

  configure.cflags  -fast
  configure.ldflags  -fast

Then I built and ran.  Now, emacs -Q runs, but if I run it with my regular .emacs it crashes before the .emacs has finished loading.  Here's the stack trace:

Program received signal EXC_BAD_ACCESS, Could not access memory.

Previous frame inner to this frame (gdb could not unwind past this frame)

Looks like a NULL deference from here.  I'll try again later without the Portfile change.

It definitely looks like -fast is required to demonstrate the problem.  I was able to get it to run successfully once with -fast, but the next time I ran the same binary the process zombied and now I will actually have to reboot to clear it from the process table.

Without -fast, things seem to be working normally.
