--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jerry DeLisle <[email protected]>: https://gcc.gnu.org/g:9579e3eb64ec89c4c0781bb0a59409f15c997213 commit r17-1786-g9579e3eb64ec89c4c0781bb0a59409f15c997213 Author: Jerry DeLisle <[email protected]> Date: Fri Jun 19 14:54:00 2026 -0700 fortran: Fix memory leak for array structure-constructor element [PR121972] Fix the remaining leak in pdt_86.f03. Added a new test in asan to avoid it. PR fortran/121972 gcc/fortran/ChangeLog: * trans-array.cc (has_class_alloc_comp): New helper; returns true if derived type DER has any CLASS component. (gfc_trans_array_ctor_element): Also free allocatable components when the element expression is EXPR_STRUCTURE, skipping types that contain CLASS components to avoid freeing stack-allocated _data pointers. (gfc_constructor_is_owned_alloc_comp): Likewise treat EXPR_STRUCTURE elements as owned only when the derived type has no CLASS components. * trans-expr.cc (gfc_trans_alloc_subarray_assign): Free allocatable components of the component's temporary descriptor before nulling its data pointer, for non-variable source expressions. gcc/testsuite/ChangeLog: * gfortran.dg/class_array_15.f03: Adjust expected free count. * gfortran.dg/derived_constructor_comps_6.f90: Adjust expected free count. * gfortran.dg/asan/structure_constructor_alloc_comp_leak_1.f90: New test.
