Using Rockbox 3.2, when playing FLAC files shorter than a second causes the following error:
Divide by zero at 01E56B90

Dreamlayers (Boris Gjenero) already located the source of the error so he deserves credit. Forum post of complete findings:

Here’s the bug, in flac_init():

          /* Calculate track length (in ms) and estimate the bitrate
             (in kbit/s) */
          fc->length = (fc->totalsamples / fc->samplerate) * 1000;

That’s integer division, so if the track is shorter than a second, the result is zero. For example, here’s GDB after playing Worms - Jock - Ya Can What Side Yer On.flac, Worms - Jock - Ya Numpty.flac on the r20528 5G iPod sim:

Program received signal SIGFPE, Arithmetic exception.
[Switching to thread 4880.0×818]
0x030a16d5 in flac_init (fc=0x6adfcb0, first_frame_offset=0)

  at /home/Boris/rockbox-dev/apps/codecs/flac.c:175

175 fc→bitrate = ((fc→filesize-fc→metadatalength) * 8 ) / fc→length;
(gdb) p fc→totalsamples
$1 = 16383
(gdb) p fc→samplerate
$2 = 22050
(gdb)

Attached are 3, royalty free, FLAC files that are shorter than a second so whoever takes up this task can test it out.
If any other information is needed please don’t hesitate to ask.
