I can confirm this bug (no, a segfault is not a feature!) under 5.6.0 under Linux 2.4.7 and 5.6.1 under linux 2.4.13; Note that it's not the empty list which causes the error, but the two list assignments. Either of the following also cause segfaults:

@a = (1..3);
@b = (4..42);
sub

or:

@a = (1..3);
@a = (4..42);
sub

Looks like an "oops." Not being a core perl hacker, it doesn't mean much to me, though. Others with more clue?

Update: Fixed a typo, thanks to crazyinsomniac. Also, this does not segfault under 5.6.0 on SunOS 5.8 -- smells like an OS-dependant bug to me..
