Bug ID: 89516
Summary: ICE in gfc_calculate_transfer_sizes at
gcc/fortran/check.c:5506
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Apparently a very old surprise, test-case is simplified from:
gcc/testsuite/gfortran.dg/pr89266.f90:
$ cat ice.f90
program test
character(*), parameter :: n = ''
character(*), parameter :: o = transfer ([''], n)
end program test
$ gfortran ice.f90 -c -Wsurprising
