R devel - Apr 2020 - ASAN

I'm trying to chase down a possible issue with the survival package, and 
so was trying to resurrect my ASAN version of r-devel.?? I added the 
lines to config.site for CC, CFLAGS and MAIN_LDFLAGS per section 4.3.3 
of the? 'packages' documentation, and lines to ~/.R/Makevars.

I followed that with? svn up,? tools/rsync-recommended, make distclean, 
./configure, then make.

It fails on the rebuild of MASS with the message

==15755==ASan runtime does not come first in initial library list; you 
should either link runtime to your application or manually preload it 
with LD_PRELOAD.
ERROR: loading failed
* removing ?/usr/local/src/R-devel/library/MASS?

It's not quite clear to me what to do next.

A quick check: do you have anything in LD_PRELOAD environment variable?
Third-party software like gtk3-nocsd may be using it for its own
purposes, which breaks ASan. When I build software with -fsanitize=...,
I have to explicitly unset LD_PRELOAD to get it to work.
