# Basic info <!--- Add commit SHA used to reproduce--> - Fixed point: - Encoder (fixed): n/a - Decoder (fixed): a90c34d30595b4cbe74c74d2b8cad559e16e40a7 # Bug description In the function ivas_dirac_dec_render_sf_fx() there is a wrong pointer increment, which affects the rendering of objects (at least for OSBA): BASOP, lib_dec/ivas_dirac_dec_fx.c, line 3792: ``` FOR( l = 0; l < hSpatParamRendCom->num_freq_bands; l++ ) { Cldfb_RealBuffer_fx[j2][k][l] = Madd_32_32( Cldfb_RealBuffer_fx[j2][k][l], g_fx, *tc_re_fx ); move32(); tc_re_fx++; Cldfb_ImagBuffer_fx[j2][k][l] = Madd_32_32( Cldfb_ImagBuffer_fx[j2][k][l], g_fx, *tc_im_fx ); move32(); tc_re_fx++; <-- issue is here } ``` The corresponding code in floating-point looks like this: ``` for ( l = 0; l < hSpatParamRendCom->num_freq_bands; l++ ) { Cldfb_RealBuffer[j2][k][l] += g * *( tc_re++ ); Cldfb_ImagBuffer[j2][k][l] += g * *( tc_im++ ); } ``` As can be seen, in BASOP the pointer `tc_re_fx` is incremented twice. The second time, actually `ci_fx` should be incremented. <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them.
