Fortran: fix bounds check for copying of class expressions [PR106945]
In the bounds check for copying of class expressions, the number of elements
determined from a descriptor, returned as type gfc_array_index_type (i.e. a
signed type), should be converted to the type of the passed element count,
which is of type size_type_node (i.e. unsigned), for use in comparisons.
gcc/fortran/ChangeLog:
PR fortran/106945
* trans-expr.c (gfc_copy_class_to_class): Convert element counts in
bounds check to common type for comparison.
gcc/testsuite/ChangeLog:
PR fortran/106945
* gfortran.dg/pr106945.f90: New test.
(cherry picked from commit 2cf5f485e0351bb1faf46196a99e524688f3966e)
