Nothing particular, just the convenience of not having to jump through hoops 
and include cruft for compatibility.

However, I am aware there are a lot of perl 5.6 installations out there (the 
last place I worked still used it; they brought in a contractor to help with 
upgrading to 5.8 but I don't think they actually did upgrade), and I'm 
willing to make Net::SSH2 work with 5.6, especially if met halfway by someone 
such as yourself helping with testing/changes.

I searched and found something that looks relevant:

Looks like 5.6 doesn't like "AV *" in an XS signature and requires it be typed 
as an SV * and then checked/cast (a typemap entry might work there too; it 
would be nice if the entries added can be 5.6-only (to keep the 5.8 path 
cleaner), which will probably require two typemap files).

Looks like it crashed there; if you check the core file you can probably 
determine what happened using a debugger such as gdb or dbx by looking at the 
stack trace and variables.

Sure, there is hope.  I don't have any 5.6 installations myself, though, so 
I'll need you (and any others on the list that are interested) to test and 
provide patches for 5.6 compatibility.  If you're able to do that, great, if 
not, go with the upgrade if you can :).

Glad to contribute, thanks for the feedback.
