--- Comment #1 from James K. Lowden <jklowden at gcc dot gnu.org> ---
I can appreciate it's difficult to locate the error when the compiler crashes
without reference to the source. Please try with -fflex-debug. The last 20
lines or so of the debug output (--accepting lines) should show the picture
being validated. It seems to somehow violate the preconditions for validation.
