Fortran: Assign allocated caf-memory to scalar members [PR84870]
Allocating a coarray required an array-descriptor. For scalars a
temporary descriptor was created. Assigning the allocated memory from
the temporary descriptor back to the scalar is now added.
gcc/fortran/ChangeLog:
PR fortran/84870
* trans-array.cc (duplicate_allocatable_coarray): For scalar
allocatable components the memory allocated is now assigned to
the component's pointer.
gcc/testsuite/ChangeLog:
* gfortran.dg/coarray/alloc_comp_10.f90: New test.
