Hello,

I got core while pressing enter to do a text selection in tmux 1.8 on Solaris.
Here is the backtrace:

Hi

IIRC this is a bug in Solaris libcurses. I think when we found it before
someone reported it to whoever owned Solaris at the time and they said
they weren't going to fix it.

I suggest you just turn off set-clipboard.

Anyone have a bug number for this?

I maintain tmux for Solaris and will be glad to take a look.
