Invoking uninitialised continuation causes segfault

When an uninitialised Continuation object is invoked, Parrot segfaults (see attached code).

The problem is a simple failure to check for a NULL pointer in pmc/continuation.pmc. I've created a patch (against r42892) that fixes the issue on my machine. make test reports no failures. Patch created with svn diff in working copy root.

The patch does not apply cleanly to current trunk. I tried applying it manually to Continuation.invoke, but the build fails when building PGE/builtins.pg.

I also will note that on my machine at least, the test case you provide does not segfault with current trunk. It doesn't actually do anything. This program:

.sub 'main' :main
    $P0 = new 'Continuation'
    say "Done"

silently exits without printing anything.

Can you update your working copy, and try again?
