PR 78534 Modify string copy to avoid -Wstringop-overflow warning
When the character length is changed from int to size_t the existing
algorithm causes a -Wstringop-overflow warning with -O1 on the
gfortran.dg/allocate_deferred_char_scalar_1.f03 testcase. This change
is committed separately from the character length size change in order
to make bisecting potential performance issues easier.
