This is a resource limit problem. If you exceed the heap size (or stack size, if they grow towards each other) limit, malloc is going to fail.

GNU bash, version 4.4.12(1)-release (x86_64-unknown-linux-gnu).

If function has more than about 32 000 discrete commands then it segfaults with malloc error.

Simple example at https://pastebin.com/2C4h4nPU

This might seem an irrelevant bug (who writes 32 000 line functions anyway?) but can cause problems with autogenerated scripts.
