Bug #: 54208 Summary: compilation error for ubound construct in PARAMETER statements Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: carlos.a.c...@nasa.gov The following reproducer: program testit integer, parameter :: n=2 integer, dimension(1-min(n,2)/2:n) :: arr integer, parameter :: i=ubound(arr,1) write(6,*) i end program testit fails to compile: >gfortran testit.F90 testit.F90:4.33: integer, parameter :: i=ubound(arr,1) 1 Error: Array 'arr' at (1) is a variable, which does not reduce to a constant expression This error causes a problem when compiling GISS's climate model (modelE), which has similar constructs, but it is not a problem with other compilers (e.g. intel 12.1) Additional information: ----------------------- >gfortran --version GNU Fortran (GCC) 4.8.0 20120401 (experimental) Copyright (C) 2012 Free Software Foundation, Inc. >gcc -v -save-temps testit.F90 Using built-in specs.
