Segfault in Debian 10 #1

sip-lab was failing to build on Debian 10. We did the necessary adjustments but running

  node samples/simple.js

is resulting in crash. Running under gdb we see:

Problem was at _addon_log (src/log.cpp). We had to enclose call to printf() within flockfile(stdout) and funlockfile(stdout).
