New description:

 I updated MacPorts yesterday, and now the parcellfun function from the
 general package is unusable. Here's a simple test file:

 {{{
 function foo()
   parcellfun(2, @myfunc, {pi; e});
 end
 function myfunc(val)
 end
 }}}

 When I run it, I get:

 {{{
 parcellfun: 0/2 jobs doneoctave(17310,0x7fff7c400180) malloc: *** error
 for object 0x108b93220: pointer being freed was not allocated
 *** set a breakpoint in malloc_error_break to debug
 panic: Abort trap: 6 -- stopping myself...
 attempting to save variables to 'octave-core'...
 save to 'octave-core' complete
 Abort trap: 6
 }}}

 I've found mention of this error going back some months on various forums,
 but I've found no clear explanation nor solution/workaround. It worked
 fine since I last updated MacPorts within the last week or two.

 {{{
   octave-devel @3.6.4_9+atlas+docs+fltk+gcc47+x11 (active)
