Bug ID: 104684
Summary: ICE: 'verify_gimple' failed (Error: non-trivial
conversion in 'component_ref')
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
gfortran-12.0.1 20220220 snapshot (g:e49508ac6b36adb8a2056c5a1fb6e0178de2439d)
ICEs when compiling the following testcase, reduced from
gfortran-bugs/gfortran-20220127.f90 from the Neil Carlson's Fortran Compiler
Tests repository[1], w/ -fcoarray=single or -fcoarray=none:
program main
type :: index_map
integer, allocatable :: send_index(:)
end type
type(index_map) :: imap
contains
subroutine sub(this)
type(index_map), intent(inout), target :: this
type :: box
integer, pointer :: array(:)
end type
type(box), allocatable :: buffer[:]
allocate(buffer[*])
buffer%array => this%send_index
end subroutine
end program
