graphite_crash.i: In function 'border_mirror_480':
graphite_crash.i:17:6: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
It doesn't happen reliably to me with -v -Q, so I can't check with gdb.
