I can confirm this problem on OSX 10.8.5.

I don't know how to solve it, but I have noticed that there is a
programming error that occurs earlier in the output, probably due to some
removed empty staves.  If this were my file, I would try to track down
that programming error.  I think it may be related.

Fitting music on 79 or 80 pages...
Drawing systems...
programming error: could not find this grob's vertical axis group in the
vertical alignment

programming error: could not find this grob's vertical axis group in the

Note that this error mentions a missing vertical axis group, which is a
container that holds staves.  Perhaps some grob is trying to be generated
that is tied to a staff that has been removed.

I have also noticed that the maximum memory used by LilyPond at the time
the malloc error was thrown was about 2.45 GB.

And I have confirmed that if I leave the layout block in, but comment out
the RemoveAllEmptyStaves, there is no malloc error.  So the problem is
clearly with removing the staves.  I believe that if you can track down
the source of the programming error it will fix your malloc problem.

But I don't have the time to go through your enormous score and track down
the source of the programming error.  There are some suggestions in the
documentation:

Good luck!
