Re^2: New to me crash message

I'm stumped about the reference to "aelem" in the error message

It is internals-speak for "array element", at the C level. It only surfaces when you grovel deeply in magic, or XS.

More precisely, it's one of the opcodes that implements `$a[$i]`. (There appears to be a `aelemfast` as well.) `$ perl -MO=Concise -e'$a[$i]' 7 <@> leave[1 ref] vKP/REFC ->(end) 1 <0> enter ->2 2 <;> nextstate(main 1 -e:1) v ->3 6 <2> aelem vK/2 ->7 4 <1> rv2av sKR/1 ->5 3 <#> gv[a] s ->4 - <1> ex-rv2sv sK/1 ->6 5 <#> gvsv[i] s ->6 -e syntax OK` [download] But oddly, there's no array indexing at the source line number given by the message.

$a[$i]

aelemfast

$ perl -MO=Concise -e'$a[$i]'
