It's surprising to me, since that is 50 * 8192 = 400K char * pointers,
which is likely 1600K bytes (assuming a 32-bit machine). Not tiny,
but well within the scope of modern machines. The strings themselves
are what will take a lot of space, unless a lot of the pointers are
NULL or something. There would seem to be something else going on.
Can you reduce this to the smallest failing example?
