Note that there's a mismatch in order indexing and allocation in bseresampler.cc in several places:
# 418
fir_compute_sse_taps (const vector<float>& taps)
{
const int order = taps.size();
vector<float> sse_taps ((order + 6) / 4 * 16);
# 470
AlignedArray<float,16> random_mem (order + 4);
for (uint i = 0; i < order + 4; i++)
random_mem[i] = 1.0 - rand() / (0.5 * RAND_MAX);
# 362
fir_process_4samples_sse (const float *input,
// ...
for (uint i = 1; i < (order + 6) / 4; i++)
{
out0_v.v=_mm_add_ps(out0_v.v, _mm_mul_ps(input_v[i].v, sse_taps_v[i*4+0].v));
In the above snippet, input_v == random_mem. It is allocated as order+4 and indexed as order+6.

Compiling beast as follows crashes the resampler.
