Constraint_Error is a run time exception. The compiler cannot detect all
possible errors. Some are detectable only at run time. The GNAT
compiler identifies the location in the code where a Constraint_Error
was raised. It is up to the programmer to the trace through the code
to determine the initial cause of the error. Often the initial cause is
improper logic some distance from the location where the exception
is raised. In the case of the thread mentioned above, the error was
caused primarily by unfounded assumptions made by the OP.
According to the RM the compiler and run time system behaved
properly.
