g95 actually gives only a warning if the variable is not set at all, it does not give a warning, if it is only set in the if branch. So does ifort. (NAG f95 and sunf95 don't give any warning neither with assigning it in the if branch or not assigning it at all.) Using -Wall gfortran states that the variable "x" is not used, but a default warning that "A dummy argument with an explicit INTENT(OUT) declaration is not given an explicit value." is more helpful. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28004
