Undefined variable ends up as garbage

Hello,

I have found a possible bug in nginx. I had a variable defined with
“set” and
used with “fastcgi_param” in one of virtual hosts definition. Then I
copied
the site file to create a new virtual host. I’ve removed the “set” line,
but
not the “fastcgi_param” one. It caused random bytes to be inserted into
that
fastcgi parameter. Everything else was OK, but those random bytes look
suspicious (possible memory violation?)

I’m using nginx/0.6.32, debian build.
