--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Instead of nullifying (internally) the "str_value", the compiler tries to set
the unallocated string to the value 0 followed by space padding.
The call path is: gfc_trans_structure_assign -> gfc_trans_subcomponent_assign
-> gfc_trans_scalar_assign -> gfc_trans_string_copy.
I think the issue is effectively the same as PR57959
