Sorry, I should have been more specific. I do have gdb installed
(actually I'm using lldb which comes with xcode, because gdb needs to
be "codesigned" before it is allowed to debug anything on the Mac).

My problem actually was how to attach the debugger to the real-time
process (since the GUI launches it), but I've since figured that out.
;-)

Ok, so now it turns out that on the Mac, disis_munger~ still crashes
Pd with an `EXC_BAD_ACCESS (code=EXC_I386_GPFLT)` (whatever that is,
but it looks like some fancy kind of segfault to me). lldb backtrace
is attached, in case any Mac experts on this list can help figuring
out what exactly might be going wrong there.

It's in a slightly different location than the crashes I had earlier,
which is no big surprise since I'm linking against the single-threaded
flex lib now. But it still has something to do with the flext queue
stuff. Not sure whether there's still some bug lurking in
disis_munger~ there, or whether flext is acting up on macOS. Has
anyone *ever* successfully run any flext Pd external on the Mac
before?
