after a Base System upgrade Passenger fails on
startup with this error:
nginx: [alert] Unable to start the Phusion Passenger watchdog: it seems 
to have been killed with signal SIGABRT during startup (-1: Unknown 

Can please someone try and reproduce and/or
suggest a workaround/fix?

How to reproduce:
- stable 11.2
- install nginx or apache (same problem with
- install (almost) any passenger version (I
   could reproduce with 5.2.1, 5.3.2 (current
   in ports) and 5.3.3 (latest))

What you get:
# service nginx start
Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is 
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is 
Starting nginx.
nginx: [alert] Unable to start the Phusion Passenger watchdog: it seems 
to have been killed wit

*** ERROR ***: '/usr/bin/gdb' is broken on FreeBSD. Please install the

I already tried:
- on another hardware, just in case
- virtual / real metal, no difference
- gdb reports the SIGABRT is actually
   raised by boost when spawning the watchdog

I had the module working on 11.1 stable:

Any suggestion is also very welcome. Thank you.
