Bug ID: 105170
Summary: Invalid finalization in intrinsic assignment
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: baradi09 at gmail dot com
Target Milestone: ---
Created attachment 52754
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52754&action=edit
Minimal working example demonstrating the bug
I have a derived type (TWrapper), which has a component with defined
assignment. The containing derived type itself has no defined assignment. Upon
an assignment between two TWrapper instances, a copy of the RHS seems to get
finalized.
The attached MWE demonstrates the problem.
Expected output (as delivered by current Intel and NAG compilers):
RefCounter_final, id:0
TRefCounter_init: id:42
-> Assignment wrapper2 = wrapper
TRefCounter_final, id:0
TRefCounter_final, id:0
TRefCounter_assign: this%id, other%id: 0 42
GFortran output:
TRefCounter_final, id:0
TRefCounter_init: id:42
-> Assignment wrapper2 = wrapper
TRefCounter_final, id:42
TRefCounter_assign: this%id, other%id: 0 42
One finalization seems to be missing. Additionally, the finalized instance
seems to be a copy of the RHS. (A copy, because after the finalization, the RHS
still seems to have kept its id-value...)

--- Comment #1 from anlauf at gcc dot gnu.org ---
With current gcc-14 trunk and also current 13-branch I get the result
you expect. Likely fixed by Paul's big finalization patch.
Can you please check?

Thanks, with 13.2.0, it seems to behave correctly.
