Comment:

 >>don't believe the compiler is the right place to solve it\\
 It is established that you do not know the Ada language compiler.\\
 If you close this ticket, you do not correct anything and you forget. I
 reopen
 it even if you do not follow it, someone else later will take it into
 account for a more complete exploitation.
 I think your answer is an arbitrary answer. Often the answers of some of
 you that do not
 relate to a bug are arbitrary and seems to be controlled by anything other
 than rational reason. You are forty people on the Committee, your opinion
 alone does not make law to close this ticket.
