Bug ID: 105380
Summary: ICE in gfc_conv_array_initializer, at
fortran/trans-array.cc:6317
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Something has changed between 20220306 and 20220327,
relevant especially for release versions :
$ cat z1.f90
program p
type t(n)
integer, len :: n
end type
type t2(m)
integer, len :: m
type(t(1)) :: a(m)
end type
type(t2(3)) :: x
end
$ gfortran-12-20220306 -c z1.f90
