[help-cgicc] debugging help: dying in the constructor

[Jay Sprenkle]

Good morning,

I'm trying to debug a small cgi program and having a lot of trouble.
It's throwing an exception in the constructor for CgiEnvironment (that's
called from the constructor from Cgicc).
This is the first executable step in my program :(
It tries to read 60 chars from cin (CONTENT_LENGTH=60) and the read
method returns 0 characters read.
This is during a POST operation. I don't know if it's the compiler,
cgicc, or the web server.
Calling the same cgi manually without the POST works ok so it appears to
be just that one path through the code.
It really looks like there's nothing in stdin, or something has read it
already.
Any suggestions?

OS: Gentoo linux,  Webserver: Lighttpd,
compiler:
gcc --version:
gcc (GCC) 3.3.5  (Gentoo Hardened Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1)

I modified the page to post to a shell script to get the environment and
it looks just fine:
