(The latter is also a segfault, btw.)

I've poked around a bit with gdb.  Both crashes happen in the same
place:

#0  0x0000000040d18810 in FLAC__lpc_compute_residual_from_qlp_coefficients_wide
    (data=0x49e4c014, data_len=110, qlp_coeff=0x7f7ffffece70, order=1, 
    lp_quantization=14, residual=0x4fced000) at lpc.c:745
745                                                     residual[i] = data[i] - (FLAC__int32)((qlp_coeff[0] * (FLAC__int64)data[i-1]) >> lp_quantization);
(gdb) i loc
i = 0
sum = 70368744161280

Alas, I don't see anything wrong there.  Also, I can evaluate that
expression in gdb just fine.

Hmm.
