Sure I will.

In the meantime: The error occurs compiling AutoApply_debug.cmm:

> ../compiler/ghc-inplace -H16m -O  -static -I../gmp/gmpbuild -I. -#include 
HCIncludes.h -fvia-C -dcmm-lint  -hisuf debug_hi -hcsuf debug_hc -osuf 
debug_o -optc-DDEBUG   -c AutoApply_debug.cmm -o AutoApply_debug.debug_o

that has been generated by:

> ../utils/genapply/genapply  >AutoApply_debug.cmm

And the pointer tagging patch has a number of changes to GenApply.hs:

So I do see some potential for an effect here.

I had earlier captured the two versions of AutoApply_debug.cmm, they are 
different, so I have attached them. I will get back with the raw_s files 
later.
