This patch fixes an error in the compiler whereby a spurious constraint
error is raised at runtime on type conversions between
access-to-discriminanted types when the object being converted is null.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* checks.adb (Make_Discriminant_Constraint_Check): Add check for
null when the type being converted is an access type.
