Paolo,

I get the same behavior but different error codes and memory usage
info.

IDL> a=bytarr(1000,1000,1000)
IDL> b=bytarr(1000,1000,1000)
IDL> c=bytarr(1000,1000,1000)
IDL> d=bytarr(1000,1000,1000)
idl(344,0xa0488fa0) malloc: *** mmap(size=1000001536) failed (error
code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
% Unable to allocate memory: to make array.
Cannot allocate memory
% Execution halted at: $MAIN$

but my activity monitor only shows 131MB free

I am on IDL 6.4.1 and OSX 10.5.2.

Is this an activity monitor difference only?

Cheers,

Brian
