Hi,
Sorry for a slow response.

Similarly:
| $ dash -c 'x() { x; }; x'
| Segmentation fault (core dumped)
It's a stack overflow. Perfectly safe, but probably disconcerting.
gawk handles this by catching the SIGSEGV and reporting it, but I'm
not convinced it's worth the extra code to do that in dash. Maybe
the manual page should warn about it. Ideas welcome.
Thanks for reporting,
Jonathan
