http://irclog.perlgeek.de/perl6/2014-05-22#i_8761466 might be relevant. I recall some work on this since but a quick search didn't show it. Have you visited #perl6? timotimo is on their often.

Hello,

indeed, the discussion raiph linked to is very closely related to this bug; After jnthn explained to me what exactly happened, I was able to fix it in MoarVM. If you used --gen-moar to build your MoarVM, you may not have a sufficiently new MoarVM; if you --gen-moar=master, it should work.

MoarVM/MoarVM/c511cb7 is the commit where the problem gets fixed. MoarVM's NativeCall implementation used to treat every Code Object with the same CUID (compilation unit ID, a compile-time created identifier) as the same object. The clicked method of the Button generates two different closures (one for each button instance), but only one is ever called back from Gtk when a click happens.

Since you said the bug still persists on the JVM backend, I'll leave this bug open until that is sorted. It likely needs about the same fix.

@timo you can use the syntax " MoarVM/MoarVM@c511cb7 " to link to a commit in a separate repo :)

Is this still an issue with the latest?

Is this still a bug? I'll close this for now.
