Hi Dmitry, So it's not explicitly in your report, but it looks like the crash is due to a divide-by-zero at: min_coef = silk_DIV32_16( silk_int16_MAX, silk_RSHIFT( psSilk_VAD->counter, 4 ) + 1 ); which happens because counter is -16 (which means (-16 >> 4) + 1 == 0). Now, this could be caused by an integer wrap-around, but it should only happen after encoding around 2 years and 9 months of audio (1 year and 4 months for 1...
