Aha, so that's the culprit. I really think we should be outputting in an exact
format, not via conversion to/from decimal.

Yep, in the $target/libstdc++-v3 build dir:

make check
RUNTESTFLAGS=conformance.exp=ext/random/k_distribution/operators/serialize.cc

You can also use shell wildcards e.g. RUNTESTFLAGS=conformance.exp=ext/*
