FAIL: test_UDPNet with pcre 8.43

[masaori335]

I saw below unit test failure with pcre-8.43 (installed via homebrew) on macOS.

$ ./test_UDPNet
REGRESSION_TEST initialization begun
REGRESSION TEST UDPNet_echo started
Echo Server port: 64351

UDP Echo Server exit failure

I haven't looked at root cause, but when I downgrade pcre to 8.42, the failure is gone.

FWIW, the commit on homebrew to down grade pcre to 8.42 is 2d60d48733fe5633939c01e1e88312ab381e02f6.

Steps to downgrade pcre:

$ brew uninstall --ignore-dependencies  pcre
$ cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
$ git checkout 2d60d48733fe5633939c01e1e88312ab381e02f6
$ HOMEBREW_NO_AUTO_UPDATE=1 brew install pcre
