FS#12442 - [Fuze+] Flac undefined instruction when going from mp3 to flac
This is probably related to the sansa fuze+ port rather than to the codec… I'm reported this one separatly from FS#12429 for it is very easy to reproduce on the device.
It occurs everytime the player has to goes from reading mp3 file to reading flac file. This does not involve generating dynamic playlist for even skipping from file A to B inside a predefined playlist will cause it. The reverse isn't true: from flac to mp3 doesn't crash the player.

Alternatively we also get data abort:
Data abort at 6006BB10
FSR 0x8
(domain 0, fault 8)
address 0x65E85284
backtrace start
pc: 0x6006BB10
sp: 0x60000118
backtrace end
or:
Data abort at 6006BB10
FSR 0x8
(domain 0, fault 8)
address 0x63E74578
backtrace start
pc: 0x63E74578
sp: 0x00005280
backtrace end
(Those 2 data abort were get with flac 5.1 (so mainly another bigger kind of flac)
this address 0x00005280 seems to appears quite often (I get other value for "at X" but sp: 0x00005280 or 0x00005390)
Buschel has made some test on another device and confirms this should be fuze+ related
another one:
Undefined instruction at 63E832E0
backtrace start
backtrace end
I can reproduce 63E832E0 crash… According to find_addr.pl this points to _plugin_end_addr in flac.elf
