LABEL_REGION [message #5576]

Hello,

LABEL_REGION (IDL 4.01) has a nasty behaviour :

IDL> d=361
IDL> a=(indgen(d,d) mod 2)^2
IDL> b=a*rotate(a,1) ; produce a dot-pattern
IDL> a=label_region(b)
Bus error(coredump)

if the number of regions exceeds 2^15(or something like this),
it ends the IDL-session ungracefully. With d=363 I got a
-- Memory fault(coredump) (on a SGI), with d=361 a
Segmentation fault(coredump). Is there a version around,
which allows for more regions - i. e. switches to long integer if
necessary? or at least catches the error?

Thanks in advance

Regards,
