re PR fortran/41478 (Corrupted memory using PACK for derived-types with allocated components)
2010-01-14 Paul Thomas <pault@gcc.gnu.org>
PR fortran/41478
* trans-array.c (duplicate_allocatable): Static version of
gfc_duplicate_allocatable with provision to handle scalar
components. New boolean argument to switch off call to malloc
if true.
(gfc_duplicate_allocatable): New function to call above with
new argument false.
(gfc_copy_allocatable_data): New function to call above with
new argument true.
(structure_alloc_comps): Do not apply indirect reference to
scalar pointers. Add new section to copy allocatable components
of arrays. Extend copying of allocatable components to include
scalars.
(gfc_copy_only_alloc_comp): New function to copy allocatable
component derived types, without allocating the base structure.
* trans-array.h : Add primitive for gfc_copy_allocatable_data.
Add primitive for gfc_copy_only_alloc_comp.
* trans-expr.c (gfc_conv_procedure_call): After calls to
transformational functions with results that are derived types
with allocatable components, copy the components in the result.
(gfc_trans_arrayfunc_assign): Deallocate allocatable components
of lhs derived types before allocation.
