One can crash calling rakudo on a file containing

eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';

or by executing thrice the line
class A { has $.a}; my $a = A.new()
interactively in rakudo.
This is reproduceable on Mac OS X Leopard and cygwin.
The stack seems strange to me, it seems that the context of the eval
is left on the stack when it should not as a result we have many
runloops in the stack.

The stack trace is :

@coke - Status changed from 'new' to 'open'

Can someone verify this against a recent rakudo?

With an Altanta-era rakudo, this works fine:

$ cat foo.p6
eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';
say "alive";
$ ./perl6 foo.p6
alive

Assigning ticket to moritz in case he can wishes to add this as a test.

Thanks for the report!
