Bug ID: 105205 Summary: Incorrect assignment of derived type with allocatable, deferred-length character component Product: gcc Version: 11.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: townsend at astro dot wisc.edu Target Milestone: --- I've run into problems with assignment of derived types containing an allocatable array of deferred-length strings. Example program: --- program alloc_char_type implicit none type mytype character(:), allocatable :: c(:) end type mytype type(mytype) :: a type(mytype) :: b integer :: i a%c = ['foo','bar','biz','buz'] b = a do i = 1, size(b%c) print *,b%c(i) end do end --- Running with gfortran 10.2.0 or 11.2.0, I get the output: >> foo << If I hard-code the length of the c component (to, say, 3), I get the expected output: >> foo bar biz buz << It seems as if only the first element of c is being copied correctly. cheers, Rich
