[Rd] error in memCompress() in make check

[Prof Brian Ripley]

So it seems that there is something wrong with the liblzma library 
used on that machine.  Did it use the version supplied with R or an 
external library (which is the default if one is found)?  My first 
step would be to force the internal version via --with-system-xz=no.

That error appears to be LZMA_MEM_ERROR: see xz/api/lzma/base.h .
