Ignoring the one-character typo of "bash" instead of "dash", I do believe this is a separate bug; dash and bash have significantly different codebases, as I understand it?

dash /does/ segfault with an identical testcase to bash, just later.

Sorry, apport sometimes reports the same bug twice, and as everything was the same (title, description, etc.) only the package was different, I thought it might be an apport mistake. Sorry for the confusion, my mistake, reverted, unduped issue. Thanks for the note.

I can confirm that this bug is also present in the package "dash 0.5.5.1-7.2ubuntu1". Another way to reproduce this bug is:
$ dash -c 'x() { x; }; x'

This appears to be Debian bug #579815 (where it has a severity of "wishlist").
