Yes, actually. See, its dying in the seg test already with:

-- Open intervals
SELECT '0..'::seg AS seg;
! ERROR: floating-point exception
! DETAIL: An invalid floating-point operation was signaled. This
probably means an out-of-range result or an invalid operation, s
uch as division by zero.
SELECT '0...'::seg AS seg;
! ERROR: floating-point exception
! DETAIL: An invalid floating-point operation was signaled. This
probably means an out-of-range result or an invalid operation, s
uch as division by zero.

You need to attach a debugger to find out where that error is actually
happenening. Just startup the backend, connect to it and connect gdb to
the newly spawned backend and just run that query by hand. Then you
should get the backtrace at SIGFPE.

Have a nice day,
