On a digital unix alpha with idl 4.0.1b:

IDL> printf,1
% PRINTF: File unit is not open: 1.
% Execution halted at: $MAIN$
IDL> printf,0
IDL>

So no crash, but no error message either.

Also,

IDL> printf,-1

IDL> printf,-2

IDL> printf,-3
% PRINTF: File unit is not within allowed range: -3.
% Execution halted at: $MAIN$
IDL>

Wonder what file units -1 and -2 are?
