After banging my head against the wall that is memory-sanitizer for a while, I finally figured out that the multiprecision failures are caused by external libraries (gmp, mpfr etc) not being built with sanitizer support. I've changed the configuration tests to trigger memory-sanitizer errors when this is the case, so that these will no longer be built in that case. However, you will need to manually delete the Boost.Build configuration caches (or all of bin.v2) in order for the fix to take effect, as these appear not to be subject to dependency-checking :(
What if I build sanitised versions? How many dependant libraries would need to be built? Ben
