<br>
Sorry, I should have been more specific. I do have gdb installed<br>
(actually I'm using lldb which comes with xcode, because gdb needs to<br>
be "codesigned" before it is allowed to debug anything on the Mac).<br>
<br>
My problem actually was how to attach the debugger to the real-time<br>
process (since the GUI launches it), but I've since figured that out.<br>
;-)<br>
<br>
Ok, so now it turns out that on the Mac, disis_munger~ still crashes<br>
Pd with an `EXC_BAD_ACCESS (code=EXC_I386_GPFLT)` (whatever that is,<br>
but it looks like some fancy kind of segfault to me). lldb backtrace<br>
is attached, in case any Mac experts on this list can help figuring<br>
out what exactly might be going wrong there.<br>
<br>
It's in a slightly different location than the crashes I had earlier,<br>
which is no big surprise since I'm linking against the single-threaded<br>
flex lib now. But it still has something to do with the flext queue<br>
stuff. Not sure whether there's still some bug lurking in<br>
disis_munger~ there, or whether flext is acting up on macOS. Has<br>
anyone *ever* successfully run any flext Pd external on the Mac<br>
before?<br>
