fastcgi_cache_purge line in config causes segmentation fault since 1.7.8 in nginx-extras

December 16, 2014 05:36AM
Hello;

for many months I've been running the config shown here: https://rtcamp.com/wordpress-nginx/tutorials/single-site/fastcgi-cache-with-purging/

This morning, I apt-get upgraded and got nginx 1.7.8 and a load of dead sites. running nginx -t gave me a segmentation fault (core dumped) error.

After a whole load of panicking and commenting one line out at a time, I finally tracked it down to this section:

location ~ /purge(/.*) {
fastcgi_cache_purge WORDPRESS "$scheme$request_method$host$1";
}

If I comment that out, I can start up wordpress and nginx -t doesn't core dump.

I can't see anything obvious in the release notes that would cause this, server details are below:
