This is invalid code, INT is not allowed in a specification expression.

------- Additional Comments From tobi at gcc dot gnu dot org  2004-12-09 00:47 -------
The problem is that we insert a function call to convert IMAX to default real,
and check_inquiry does not support these conversion functions.

Subject: Re:  ICE with computed array declaration

This example is from the software copygb
(ftp://ftpprd.ncep.noaa.gov/pub/cpc/wd51we/copygb) which was ported
from generic Fortran95 to g95,
and thus compiles perfectly with g95, but not with gfortran.
