Looks like some stack issue, or maybe an exception in a non-main
thread:

See that chkstk above?

Also, how can cursor_type be 6?  The enumeration has only 6 values, 2
of them negative.

Other than that, I cannot glean anything useful from this backtrace,
especially since this is an optimized build.

Is this GDB session still alive?
