@[x;0;1+] 1 and {@[x;0;y]}[1;1+] #559

Closed tavmem closed 4 years ago

tavmem commented 4 years ago

This issue was identified by adam.antonik@gmail.com

The expression
@[x;0;1+] 1
segfaults.
I'm not sure what x is supposed to be referring to here, 
changing x to 'a' produces a value error.  

However the slightly more sensible
{@[x;0;y]} [1;1+]
also dies.
