This, or some, variant has been reported multiple times.
Like in most programming languages, you can easily write programs that
behave badly,
in this case you are exhausting the stack has there is no tail call
optimization.

see for instance
https://lists.gnu.org/archive/html/bug-bash/2012-09/msg00073.html
and the following discussion
