mod_auth_cas causes sigfault

[Trenton D. Adams]

Hi Phillip,

First, I'm assuming that it's got to be some sort of configuration error, right?  I mean I have a hard time believing that everyone else hasn't seen this, except me, and having it be a problem with the code.  Although, if it is, the code should be changed to print errors when that occurs.  But, it appears to set default values for every config item.  

I enabled debug mode, and still nothing from mod_auth_cas is printed to the logs.  Then, just for kicks, I did the debug replacement you suggested, but obviously the same result.

It appears to occur on service validation because I get to the cas page, and back, and then it occurs, resulting in a blank page to the browser.

FYI: I'm running apache 2.2.8 on gentoo linux.

For now, I will start adding some extra debugging statements to the code, to find out where it's blowing up.  If you have any suggestions in the mean time, let me know.

Thanks.
