Details

It appears that wma files with samplerate of 48kHz don't work with rockbox - is this a known limitation? I couldn't find anything on the wiki.

(I suppose there could be another problem with the files, but the samplerate is what they have in common)

An example can be found here:

The symptoms are slightly different depending on target:

m:robe 100: Data abort at 01F03400 (0)
gigabeat f: track is skipped
simulator: segmentation fault

I spent a couple hours digging through this and made no progress. WMA decoders do not need distinguish between 44.1 and 48kHz, so there is no obvious reason this should fail. I did notice that the error condition changes depending on what debug statements I use though, which makes me think there is an overflowing pointer somewhere that only occurs at 48khz.
