Re: Memory leak in examples

Dimitry,

Please take a look at this c.l.a post from Marc A. Criley:

For Ada 95, I only managed to find this:

http://www.adahome.com/rm95/rm9x-13-11-02.html

"(11)  It is a bounded error to free a discriminated, unterminated task
object."

So, as far as I can understand it, in Ada 95, if the task is not
discriminated, you can call Free on an access to it.

Last but not least, the fix actually works under load from a test script.
