Re: non-deterministic test failure: _clos1way2

[arnold]

Hi.

Thanks for the bug report.

This sort of error shows up on (say) Ubuntu when running the checks
under valgrind. It does happen also some legacy Unix and (IIRC) BSD
systems.  Any idea what might be the difference between Guix and
Ubuntu that would cause this?

In any case, although it's annoying that the test fails, it's not
indicative of any kind of major problem and you can use the gawk
that you've built.

Thanks,

Arnold
