I don't know what IDLUTILS is, but are you certain that it can be compiled in
64bit mode and work correctly? The most likely explanation is that the code is
not 64bit safe, usually because it makes assumptions about the size of pointers
which are not valid in 64bit. with the typical result being bus errors and seg.
faults.

No further insight but the same symptom and the same workaround!
I have sent a support request to Creaso (German IDL dist). Seemingly
ittvis is still searching for an explanation.
