https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50410 --- Comment #48 from anlauf at gcc dot gnu.org --- Created attachment 55666 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55666=edit Inremental patch This is a cut-down and revised version of the patch by Tobias that deals with invalid allocatable and pointer components in data statements, and adjusted to F2018, and fixing the issue mentioned by Steve. I've removed the other part that tries to detect the double initialization. I think this is the wrong place as is would not detect e.g. the following: program p type t integer :: g end type t type(t) :: u data u /t(3)/ data u%g /2/ end A better-suited place is probably the loop in gfc_assign_data_value, but find_con_by_component seems not to be able to handle the current situation.
