Bug ID: 83154
Summary: ICE: associate and coarrays
Product: gcc
Version: 8.0
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 program bug.f90 causes an internal compiler error. It seems the
implementation of the associate facility for coarrays is not complete. Some
features are implemented, though (see PR78152).
program co_assoc
implicit none
integer, parameter :: p = 5
real, allocatable :: a(:,:)[:,:]
allocate (a(0:p+1,0:p+1)[2,*])
associate ( &
b => a(1:p, 1:p), &
c => a(0:p-1, 1:p ), &
d => a(2:p+1, 1:p ), &
e => a(1:p , 2:p+1), &
f => a(1:p , 0:p-1))
end associate
end program co_assoc
