Hi Tristan,

Thanks very much.  There is just one small problem.  Some regressions:

I can provide you with the full logs if you like.  A quick look however 
appears to suggest that some targets are increasing the sizes of the 
memory regions, possibly for alignment purposes, and that causes the 
regexps to fail.
