Error message

[Maxime's Music]

Hi Lilyponders,

I've been working on a very big score, adding staves one at a time.

There are 34 staves, and the PDF is 107 pages long. When I add in either of the final two staves I get this error message:

lilypond(43147,0xa70c91c0) malloc: *** mach_vm_map(size=1048576) failed (error code=3)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

Can anyone point me in the right direction to start working out what is wrong?

All the best,

Craig
