Furthermore the default stacksize is 8MB, which was huge 20 years ago but nowadays is really small for data storage.

(An even longer time, before Linux existed, I tried to copy the screen 32k bytes frame buffer in the C stack. It did not end well.)

Stacks are quite useful data structure, but one should use a separate stack for data with a much larger hard limit.
