I've found an ugly bug with the NCOMPLEMENT keyword to where(), first
introduced in IDL v5.4.

IDL> wh=where(1,NCOMPLEMENT=ncnt)

causes a segfault, in v5.4 and v5.5, under Linux at least. It only
occurs if NCOMPLEMENT is used, but the corresponding COMPLEMENT is not.
A temporary workaround is always to specify COMPLEMENT, even if you
don't need it.
