--- Comment #3 from FeepingCreature <default_357-line at yahoo.de> ---
This is one for Walter.

The proximate cause is that in elem.d, the "0" on the left side of 0 / fun(0)
is converted from a long double constant to a double constant sight unseen.
(elem.d: shrinkLongDoubleConstantIfPossible)  This leaves the operation post
inlining standing as "double / long double", which is not a valid operation.
