[Mesa-dev] [PATCH 09/22] intel/compiler: fix for memmove argument on annotating error

[kevin.rogovin at intel.com]

From: Kevin Rogovin <kevin.rogovin at intel.com>

Without this fix, disassembling of GEN shaders with GPU commands
that the disassembler does not know would result in errors being
added to the annotator which would crash when more than one error
was added.
