            Bug ID: 107210
           Summary: [13 Regression] ICE in tree_to_uhwi, at tree.cc:6392
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: asolokha at gmx dot com
  Target Milestone: ---

gfortran 13.0.0 20221009 snapshot (g:e95e91eccd022a4a3a86da2749809fbad9afd20e)
ICEs when compiling the following testcase, reduced from
gcc/testsuite/gfortran.dg/sizeof.f90, w/ -O1 -fanalyzer:

subroutine check_int (j)
  INTEGER(4) :: i, ia(5), ib(5,4), ip, ipa(:)
  target :: ib
  POINTER :: ip, ipa
  logical :: l(5)

  l = (/ sizeof(i) == 4, sizeof(ia) == 20, sizeof(ib) == 80, &
       sizeof(ip) == 4, sizeof(ipa) == 8 /)

  if (any(.not.l)) STOP 4

end subroutine check_int

% gfortran-13 -O1 -fanalyzer -c twz5zkp4.f90
during IPA pass: analyzer
twz5zkp4.f90:8:43:

    8 |        sizeof(ip) == 4, sizeof(ipa) == 8 /)
      |                                           ^
