The interval it fails on is empty here:

(gdb) f 4
#4  0x00000000006d8b2c in Tuplet_number::calc_y_offset
(smob=0x7ffff22bebe0) at tuplet-number.cc:83
83        return scm_from_double (positions.center ());
(gdb) p positions
$1 = {<Drul_array<double>> = {array_ = {4.158845306777426,
3.5388453067774259}}, <No data fields>}

I'll try to narrow it down by gutting the movement which has the
triplets.  They all look pretty benign though.

Cheers,
