[perl #126823] [MoarVM] Failing test in S32-array/adverbs.t and S32-hash/adverbs.t: Code does not die as expected with 'use '

[Christian Bartolomaeus via RT]

I just found that my golfed test case seems to be flapping:

$ for run in {1..10}; do (echo '#' > Bar.pm6; ./perl6-m -I. -e 'use Bar; my %h 
= b => 2; say %h<b>:zorp' 2>&1; ./perl6-m -I. -e 'use Bar; my %h = b => 2; say 
%h<b>:zorp' 2>&1) | grep -c 'Unexpected named parameter'; done

Sometimes the second evaluation returns '2', sometimes it gives the desired 
error. Setting MVM_SPESH_DISABLE=1 looks correct:

$ for run in {1..10}; do (echo '#' > Bar.pm6; ./perl6-m -I. -e 'use Bar; my %h 
= b => 2; say %h<b>:zorp' 2>&1; MVM_SPESH_DISABLE=1 ./perl6-m -I. -e 'use Bar; 
my %h = b => 2; say %h<b>:zorp' 2>&1) | grep -c 'Unexpected named parameter'; 
done
