--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Up to revision r258235 (2018-03-04) compiling the test gave the error

     if (.not.checkFmt(fmt)) then
             1
Error: Reference to impure function 'checkfmt' at (1) within a PURE procedure

After revision r258362 (2018-03-08) I get the ICE. This has been back ported to
7.3.1.

In this range I see only r258281, r258305, and r258347, but r258305 has not
been back ported.
