Are you getting OPUS_ALLOC_FAIL on the opus_decoder_init() too or just
on opus_decoder_create()?

when you use OVERRIDE_OPUS_ALLOC and opus_alloc(x)=NULL you're
essentially saying "I don't have a working malloc()", so none of the
calls to the *_create() functions can work, it's normal that you're
seeing those fail with OPUS_ALLOC_FAIL because there's no way the
library is able to allocate memory.

This version should actually work and I don't see how
opus_decoder_init() could return OPUS_ALLOC_FAIL since it's not
allocating anything. Are you sure that's what it returns?
