Is SPARC as picky about data alignment as PPC is? Could it be a misaligned access?

That's line 55, which is a reference to a macro, IDCT_DEQUANT_START.

Can you replace the macro reference with the actual code (i.e. via
copy and paste) and see which line in the macro actually causes the
crash?

I'm going to guess int dmf = dequant_mf[i_qp%6][0], but that makes no
sense whatsoever.
