I cannot reproduce it with a clean build (ubuntu 14.04, macOS 10.13).

Can you reproduce the issue from scratch (downloading nginx tip & njs tip in a 
separate directory)?

Somehow your ngx_http_js_module.so is linked against outdated libnjs.a.

On r450 you should see the following:

objdump -t ../njs/build/libnjs.a  | grep -E 'g.*njs_vm_'

Of course.  I'm always

  hg update --clean tip

r450 is reproducibly causing the error.

r446 is fine atm.

fyi, simple revert to

hg revert -r 446 --all

fixes the config check problem, and subsequent nginx build execs as usual

Hi compiled Nginx 1.13.9 from master branch to try out HTTP/2 Server Push
but noticed the pushed assets loose their gzip compression and are served as
non-compressed assets ? Is that as intended ? I posted my findings at
