I got a segv from Insight.
Stack trace appended.

The scenario: while debugging gcj I put a `tree' variable into the
watch window.  I looked at the tree a bit (a tree is a big hairy
union; I expanded one branch, looked around, and then collapsed it all
back to a single line).  When I `next'ed (using the GUI) over a
statement which changed the variable, Insight crashed.
