[Bug c++/79827] genautomata segmentation fault on NI-RT Linux

I raised the stack to 32768 KiB.
Then the genautomata passed without segfault.

Also other GCC segfaults disappeared.

This is a bit non-intuitive behavior.

Maybe we should introduce a warning
telling the user that the stack is suspiciously small?
