Hi,

I'm the original reporter of the bug. I forgot to mention that I limited 
the virtual memory of the process using 'ulimit -v 100000' in a bash.

I'm very new to Ada, but I'm impressed of all the features. In parallel 
I'm developing a little library to make C programming easier. In this 
library I malloc'ed some "emergency memory" at the program start which 
is simply freed when the process gets out of memory. Then the error 
handler can at least raise an exception or print some warning.

Perhaps the GNAT runtime library could use a similar approach.
