# Basic info <!--- Add commit SHA used to reproduce --> - Fixed point: - Encoder (fixed): 21cecc43 # Bug description Using the a very long file (basically any file longer than 32767 frames) cause an overflow in some counters in function ivas_ism_metadata_enc_fx() the code is located after line 800: ``` FOR( ch = 0; ch < nchan_ism; ch++ ) { hIsmMeta[ch]->last_ism_metadata_flag = hIsmMeta[ch]->ism_metadata_flag; move16(); IF( hIsmMeta[ch]->ism_metadata_flag == 0 ) { >>> hIsmMeta[ch]->ism_md_fec_cnt_enc = add( hIsmMeta[ch]->ism_md_fec_cnt_enc, 1 ); move16(); } ELSE { hIsmMeta[ch]->ism_md_fec_cnt_enc = 0; move16(); } hIsmMeta[ch]->ism_md_inc_diff_cnt = add( hIsmMeta[ch]->ism_md_inc_diff_cnt, 1 ); move16(); hIsmMeta[ch]->ism_md_inc_diff_cnt = s_min( hIsmMeta[ch]->ism_md_inc_diff_cnt, ISM_MD_INC_DIFF_CNT_MAX ); move16(); } ``` cc @vasilache, @vaclav the same problem may be happening in float as well The datatype should be change or a limit should be added to ensure it doesn't overflow # Ways to reproduce <!-- Commandline or script --> ```bash IVAS_cod -ISM 1 NULL 32000 16 longlongfile.wav bit ``` <!--- Below are labels that will be added but are not shown in description.
