So far the problem has only shown up inside Buildbot. I can't duplicate
it interactively on the same machine running as the same user.
After adding
export CYGWIN="$CYGWIN error_start=c:\cygwin\bin\dumper.exe -d %1 %2"
to test/config.sh dumpcap no longer exits prematurely. Dumper doesn't
create a core file, either. Could it be a Cygwin issue?
