Alexander,
Thanks for the info. I'm rather new to gdb, and thos two other commands
helped a lot, but not with the ipow20() call. Here's the output.
#0 0x400afa2a in lame_decode1_headersB (buffer=0x0, len=0,
pcm_l=0x112a4e5, pcm_r=0x6112a4e5,
mp3data=0x112a4e5, enc_delay=0x0, enc_padding=0x0) at
mpglib_interface.c:137
137 pcm_l[i] = *p++;
(gdb) bt
#0 0x400afa2a in lame_decode1_headersB (buffer=0x0, len=0,
pcm_l=0x112a4e5, pcm_r=0x6112a4e5,
mp3data=0x112a4e5, enc_delay=0x0, enc_padding=0x0) at
mpglib_interface.c:137
#1 0x4011ae60 in ipow20 () from /usr/lib/libmp3lame.so.0
(gdb) up 1
#1 0x4011ae60 in ipow20 () from /usr/lib/libmp3lame.so.0
(gdb) list
137 pcm_l[i] = *p++;
138 pcm_r[i] = *p++;
139 }
140 break;
141 default:
142 processed_samples = -1;
143 assert(0);
144 break;
145 }
146 break;
Also, the version is 3.93.1.
TIA,
Deven
