Thanks a lot, I found the problem, there were some enormous
statically-allocated arrays !!
Now, I allocate those arrays on startup; those arrays are used for a hash table
that contains the pointers, another solution was to create them with smaller
size.

I guess you've got an enormous statically-allocated array somewhere. If you
can take it out and instead allocate it on startup with malloc, you'll have
a much better chance.
