Revision 047c6ad752386e892afd45fd97214108e303776f authored by Ronald S. Bultje on 10 February 2012, 06:57:01 UTC, committed by Reinhard Tartler on 19 February 2012, 14:41:16 UTC
Conversion of the luma intra prediction mode to one of the constrained
("alzheimer") ones can happen by crafting special bitstreams, causing
a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).
