void gate_x1_curve(float *dst, const float *src, const dsp::gate_knee_t *c,
size_t count)
{
        gate_knee_t knee __lsp_aligned64;
        float mem[32] __lsp_aligned64;
        float stub[8] __lsp_aligned64;
        size_t mask;

you seem to rely on a specific chosen stack layout.  Instead you should
put appropriate _Alignas or __attribute__((aligned(N))) on the variables
above.
