I can only guess here, but you could try to start Pd without loadbang
as "pd -noloadbang" and see if it still crashes. Then it might help to
load some patches as single ones. That is, try to create a
[originator] object or directly open that patch (you will get some
error messages, but hopefully not a crash.

A third thing: try removing all libs from your .pdrc and add them
again one by one. Maybe there is a conflict somewhere. (You can omit
knob, it's not a library). 

And last: You will need the [prepend] from Cyclone in the Pd CVS for
Memento. This has the nasty side effect, that you cannot use the
iemlib2 which also includes a prepend, but the last one doesn't
support the set operation as cyclone's prepend does. 

Either omit iemlib2 from your pdrc, or recompile iemlib2 without
prepend. This is done easily with: 

1. moving away (rename/remove) the file iemlib_R1.12/src/prepend.c
2. edit iemlib2.c and uncomment/remove prepend everywhere here:
   line 36: /* #include "iemlib2/prepend.c" */
   line 66: /* prepend_setup(); */
3. recompile

This won't hurt any of the older patches as Cyclone's prepend does all
that IEM prepend does, too, and then some.

HTH.

ciao
