are you the one who submitted the patch with a translated
version of lpc_asm.s? I thought that was Luca.

no, that's one of the hardest things to debug. you pretty much
have to single-step through it and making sense of it requires
intimate knowledge of the decoder. that's why it takes me so
long to qualify any patches to the core encoder/decoder. there
is little forgiveness from users for bugs in those.
