While running the spectests through ASAN nwc10++ found an invalid read error
in t/spec/S32-io/IO-Socket-Async.t. Have included both ASAN and valgrind
output. Note that the valgrind output is from a 32 bit system while (I
guess) nwc10's output is from a 64 bit system.
# ASAN output

This is Rakudo Perl 6 running in valgrind, a tool for debugging and
profiling programs.
Running a program in valgrind usually takes *a lot* more time than running
it directly,
so please be patient.
This Rakudo version is 2016.11.130.gfa.82.a.1.f.85 built on MoarVM version
2016.11.25.g.4.be.6.b.384,
