Bug ID: 70817
Summary: Internal compiler error coarrays -finit-real=snan
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: physiker at toast2 dot net
Target Milestone: ---
Compiling the file t.f90 causes gfortran version 5.3 (OpenCoarrays-1.4.0) and
gcc-6.0.1-RC-20160423 (OpenCoarrays current git version) to crash with an
internal compiler error. Without the option -finit-real=snan the code compiles
without errors.
t.f90
PROGRAM f
IMPLICIT NONE
REAL(4), PARAMETER :: zero = 0.0e0_4
INTEGER :: n[*]
REAL (4) :: p[*]
REAL (4) :: h
n = 1
h = REAL(n, KIND=4)
p = zero
END PROGRAM f
