Assert in StereoDmxEVS complexity job in EVS decoder
# Basic info <!--- Add commit SHA used to reproduce--> - Fixed point: a8d5672d8743dcbb484253c068de76300d430433 # Bug description Some modes in the StereoDmxEVS complexity run trigger an assert in the decoder. The decoder is pure EVS. ``` IVAS_dec: lib_com/fd_cng_com_fx.c:1234: minimum_statistics: Assertion `msNoiseEst[j] >= 0' failed. ``` # Ways to reproduce :warning: Could not reproduce this, neither in the runner container, nor locally on my Laptop :warning: Error pattern: https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/blob/main/ci/complexity_measurements/ep_10pct_fer.g192?ref_type=heads Use runIvasCodec.py ``` python3 scripts/runIvasCodec.py -p scripts/config/ci_linux_ltv.json -m StereoDmxEvs_b07_64_wb_rs -f ci/complexity_measurements/ep_10pct_fer.g192 --oc mono -e ./IVAS_cod -d ./IVAS_dec ``` or: <!--Commandline or script--> ```bash IVAS_cod -stereo_dmx_evs -max_band wb scripts/switchPaths/sw_wb1.bin 16 COMPLEXITY/pcm/ltv48_STEREO_16_STEREO.pcm ltv48_STEREO_StereoDmxEvs_b07_64_wb_rs.192 scripts/tools/Linux/eid-xor -vbr -fer ltv48_STEREO_StereoDmxEvs_b07_64_wb_rs.192 ep_10pct_fer.g192 bit_fer IVAS_dec 16 bit_fer out.wav ``` Bitstream (zipped): [ltv48_STEREO_StereoDmxEvs_b07_64_wb_rs_fer_ep_10pct_fer_g192.zip](/uploads/353f8b2b15fe211013e2f38bacfc0bd7/ltv48_STEREO_StereoDmxEvs_b07_64_wb_rs_fer_ep_10pct_fer_g192.zip) :warning: Note: This issues seems to be reproducible only with the instrumented decoder! :warning: Occurs in frame no. 31, stack trace: ``` #3 0x00007ffff7cb96e2 in __GI___assert_fail (assertion=0x555555e941bb "msNoiseEst[j] >= 0", file=0x555555e94170 "lib_com/fd_cng_com_fx.c", line=1236, function=0x555555e943c0 <__PRETTY_FUNCTION__.30> "minimum_statistics") at assert.c:103 #4 0x00005555559899f1 in minimum_statistics (len=62, lenFFT=62, psize=0x55555601bec8, msPeriodog=0x55555601bb5e, msNoiseFloor=0x55555601b8f0, msNoiseEst=0x55555601bbda, msAlpha=0x55555601acd4, msPsd=0x55555601ab5c, msPsdFirstMoment=0x55555601b77c, msPsdSecondMoment=0x55555601b7f8, msMinBuf=0x55555601adcc, msBminWin=0x55555601a96c, msBminSubWin=0x55555601aa64, msCurrentMin=0x55555601b494, msCurrentMinOut=0x55555601b39c, msCurrentMinSubWindow=0x55555601b58c, msLocalMinFlag=0x55555601b684, msNewMinFlag=0x55555601b700, msPeriodogBuf=0x55555601c662, msPeriodogBufPtr=0x55555601c8ce, hFdCngCom=0x55555601ce24) at lib_com/fd_cng_com_fx.c:1236 #5 0x0000555555572ad6 in perform_noise_estimation_dec_fx (timeDomainInput=0x7ffffffef2d0, Q=3, hFdCngDec=0x555556019e64) at lib_dec/fd_cng_dec_fx.c:1452 #6 0x000055555556fa13 in ApplyFdCng_fx (timeDomainInput=0x7ffffffef2d0, Q=3, powerSpectrum=0x0, Q_power_spectrum=0, cldfbBufferReal=0x7ffffffec930, cldfbBufferImag=0x7ffffffec8b0, cldfbBufferScale=0x0, st=0x555555ff8454, concealWholeFrame=0, is_music=0) at lib_dec/fd_cng_dec_fx.c:746 #7 0x000055555585b23e in acelp_core_dec_fx (st=0x555555ff8454, output_fx=0x0, synth_fx16=0x7fffffff5020, save_hb_synth_fx16=0x0, bwe_exc_extended_fx=0x7fffffff66c0, voice_factors_fx=0x7fffffff66b6, old_syn_12k8_16k_fx=0x7fffffff4b10, sharpFlag=0, pitch_buf_fx=0x7fffffff4d96, unbits=0x7fffffff70f4, sid_bw=0x7fffffff4b0e, hStereoTD=0x0, tdm_lsfQ_PCh_fx=0x0, use_cldfb_for_dft=0, last_element_mode=0, last_element_brate=0, flag_sec_CNA=0, nchan_out=1, hStereoCng=0x0, read_sid_info=1) at lib_dec/acelp_core_dec_fx.c:1686 #8 0x0000555555680acb in evs_dec_fx (st_fx=0x555555ff8454, output_sp=0x7fffffff71b0, frameMode=FRAMEMODE_NORMAL) at lib_dec/evs_dec_fx.c:386 #9 0x00005555555c44c3 in evs_dec_main_fx (st_ivas=0x555555ff5534) at lib_dec/lib_dec_fx.c:5676 #10 0x00005555555bf0fb in IVAS_DEC_GetSamplesDecoder (hIvasDec=0x555555ff54c4, splitRendBits=0x0) at lib_dec/lib_dec_fx.c:4002 #11 0x0000555555562e2e in decodeG192 (arg=..., hBsReader=0x555555ff5a60, hHrtfBinary=0x7fffffffd780, headRotReader=0x0, externalOrientationFileReader=0x0, refRotReader=0x0, referenceVectorReader=0x0, objectEditFileReader=0x0, splitRendBits=0x0, hIvasDec=0x555555ff54c4, pcmBuf=0x555555ff60b0) at apps/decoder.c:2315 #12 0x000055555555e3e6 in main (argc=4, argv=0x7fffffffe218) at apps/decoder.c:707 ``` <!--- Below are labels that will be added but are not shown in description.
