*zsh* handles the "out of memory" scenario gracefully now
The *zsh* shell allocates memory while printing the `out of memory` fatal error message. Previously, if the printing routine failed to allocate memory, it triggered an infinite recursion. Consequently, the *zsh* process terminated unexpectedly due to a stack overflow. With this update, the infinite recursion no longer appears in this scenario. As a result, after printing the fatal error message, *zsh* now terminates gracefully in case it runs out of memory.
