Ok Florian, you convinced me. I know that GNAT uses malloc for memory 
allocation on its Linux implementation. Looking at malloc man page, one 
can read in the last paragraph:

"Linux follows an optimistic  memory  allocation  strategy.
This means that when malloc() returns non-NULL there is no
guarantee that the memory really is available. In case  it
turns  out  that  the system is out of memory, one or more
processes will be killed by the infamous OOM killer."

So I guess this is normal in the case of systems with virtual memory.
