Well, according to the standard (F2008 because I have it at hand):

"numeric type -- one of the types integer, real, and complex"

"For an intrinsic assignment statement where the variable is of numeric type,
the expr may have a different numeric-type or kind type parameter, in which
case the value of expr is converted to the type and kind type parameter of the
variable [...]"

Thus it is definitely valid. The question, when to warn and when not, is a
difficult one. -Wconversion does (should) warn in this case; some argue that it
is too verbose; I agree, but the last time I was thinking about -Wconversion, I
had problems to come up with rules which warn exactly as wanted.

(Regarding the rest: No idea - without access to the source it is too
inconvenient to debug.)
