squid SIGABRT on bad url_rewriter

[crypt]

Binary package hint: squid

While tried to implement videocache (http://cachevideos.com) I faced a following bug. If /etc/squid/squid.conf includes following line:

url_rewrite_program /usr/bin/python /my_path_to/videocache/videocache.py

squid failed to start:

sympho build # squid -DN
Aborted (core dumped)

I rebuilded package without striping and got following backtrace:

(gdb) run -DN
Starting program: /usr/sbin/squid -DN
[Thread debugging using libthread_db enabled]

Program received signal SIGABRT, Aborted.

Quit anyway? (y or n) y

I believe that videocache helper is misconfigured but squid must handle this situation correctly.

Thanks for the traceback this has been reported upstream.

This was fixed by the "squid" binary package built from squid3 sources in Ubuntu Xenial and later.
