The problem is ## HELLO `$ perl -MO=Deparse,-p grimy sub test_a { use warnings; use strict 'refs'; (my $arg = shift()); (ref($arg) ? $$arg->test_a([0]) : $arg); ## HELLO } sub test_b { use warnings; use strict 'refs'; (my $arg = shift()); (ref($arg) ? test_a($$arg[0]) : $arg); } use warnings; use strict 'refs'; test_b([42]); test_a([42]); grimy syntax OK` [download] The problem is indirect object syntax, to fix you need a forward declaration ( `sub test_a;` ) or parenthesis	[reply] [d/l] [select]

Nope, I don't have typos, and nope, test_b doesn't 'recurse', it just calls test_a. Only test_a is recursive, and only test_a crashes, which is why I assumed that it is the recursivity that causes problems, as you can read in my first post.	[reply]
