error: can't allocate region

[address@hidden]

Hi all,

I’m working on a very large score (about 1200 bar), and now I receive the 
following error that’s driving me crazy:

Drawing systems...lilypond(7156,0xa2db5000) malloc: *** 
mach_vm_map(size=8388608) failed (error code=3)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

I tried to isolate the problem and, from a certain bar (at the end) it’s enough 
to add a note to receive the error. Before this entry, it’s fine.
I understand that this error should be related to the memory management, but 
I’m not able to solve it…

It happens only when I work on the whole score. Isolating a fragment doesn’t 
recall it.

Any help very appreciated!!

Cheers
