Bug ID: 115700
Summary: [10/11/12/13/14 regression] Bogus warning for
associate with assumed-length character array
Product: gcc
Version: 10.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: zed.three at gmail dot com
Target Milestone: ---
The following MVCE has a bogus "used uninitialised" warning from the associate
variable "tmp":
subroutine mvce(x)
implicit none
character(len=*), dimension(:), intent(in) :: x
associate(tmp=>x) ! Bogus warning here
end associate
end subroutine mvce
Compile with `-Wuninitialized`
(in action on Compiler Explorer: https://godbolt.org/z/hjafKaGsd)
This works on 10.3 and 11.2, with the warning appearing in 10.4 and 11.3
onwards.
Possibly related to PR fortran/104228 ?
