Bug ID: 58989
Summary: internal compiler error when using reshape function
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: firefox84 at freenet dot de
When trying to compile this code
PROGRAM test
REAL(KIND=KIND(1.0d0)), DIMENSION(4,4) :: fluxes
REAL(KIND=KIND(1.0d0)), DIMENSION(2,2,2,2) :: f
INTEGER, DIMENSION(3) :: dmmy
dmmy = (/2,2,2/)
f = reshape(fluxes,(/dmmy,2/))
END PROGRAM test
with: gfortran -v -o test test.f90
I get this error message:
