My initial guess would be with the SH[RL]32 and ADD32 functions. Nice call. The culprit is SHRL32. This is not used in many places, and in most of those, the operand comes from EXTEND32. The only really suspicious instances is in lsp.c (lsp_interpolate): spx_word16_t tmp = DIV32_16(SHL32(1 + subframe,14),nb_subframes); (subframe is an int) > I just checked in changes that may fix s...
