Error(s) attempting to playback FLACs on an iPod Color/Photo

Greetings. 

iPod Color/Photo running Rockbox 3.15.  New install.

Brought over a mix of files - FLAC, aac, mp3; Rockbox also recognizes the files already installed on the Apple side of things of the iPod OS - AIFF, ALAC, mp3.

AIFF, ALAC, mp3, aac files play back fine on the iPod when running either iPod OS or Rockbox.

*SOME* FLACs play back; specifically, the files which were originally ripped from CDs on a Mac using XLD - https://tmkk.undo.jp/xld/index_e.html

Other FLACs will not play back, and generate errors which begin with "Divide by 0...," like the following:


Divide By 0 at 01e81350 (0)
pc: 01e81350 sp: 40002b28
bt end

I have tried re-importing the files in various ways:

 - rebooting into Rockbox and copying the files over

 - Rebooting into the iPod OS and copying the files over

 - Rebooting into the iPod OS and copying over a zipped folder of files, and expanding them in place

 - Rebooting into the iPod OS and copying the files over using GRsync

I removed and reinstalled Rockbox; issue persists.

The FLACs are approximately 20-40MB in size each.

Assistance is appreciated.

Now, before anyone says, "the files are corrupted," the files all play back perfectly on a variety of other players and other devices with no issue - RhythmBox, DeaDBeeF, Logitech Media Server/Squeeze/SqueezeLite, VLC, etc.

Also, it appears to be isolated to FLACs. 

My media library is a mix of various file types.  I'm using a subset of known good files to test all of this before I copy over a large amount of files.

In theory, I could just re-rip my FLACs into something else (ALAC, for instance), but that kind of negates a major point of using Rockbox - being able to play back these file formats.  If I'm just going to use file types that are supported by the iPod OS, I could just use that.  I'd rather use Rockbox.

Thanks in advance for any and all assistance.

Does it happen in the current build?  Does the same file always crash or always work?

I am running 3.15 (as indicated in my original post), which appears to me to be the current build - unless you mean the latest dev build, which I have not tried.

I've tested with a variety of FLAC files; the only common denominator for the failing ones is they were not created with XLD on one of my personal Macs (I'm currently running Linux on my primary computers - Zorin OS 15.3).  The FLACs I created on my personal Macs using XLD play back with no issue.

Newest test: I just loaded in a FLAC that is 166 MB in size.  It is a 24 bits/96kHz file downloaded from Bowers & Wilkins.  Plays back with no issue (and sounds great).

Try the current build and see if this has been fixed since 3.15.

Understood; I will try this. 

Let me know if you referring to the daily dev build, located here:

https://www.rockbox.org/daily.shtml

If not, I'd appreciate a link to the appropriate build I should try; thanks in advance.
