>Description:
I have a test PHP script that I'm trying to run as a cgi script (i.e., no php_mod... I have the appropriate AddType defined in srm.conf)... here's the bug...

If I run it from the command line (./test.php3) it executes just fine, but if I hit it with my browser Apache sends a page that says "no input selected." The log file then reports "(8)Exec format error"

The script is as the path to php, opening html headers and then the line:
<?php echo "test"; ?>

Executing on the command line results with "test"... but through Apache results in the error above.

I ran a backtrace on it and got:
Program received signal SIGINT, Interrupt
 0x4010fcf2 in __libc_accept ()
 #0 0x4010fcf2 in __libc_accpet ()
 #1 0x80701ae in strcpy ()

 rtld_fini=0x4000a350<_dl_fini, stack_end=0xbffffd3c)
 at ../sysdeps/generic/libc-start.c:78

NOTE: My web hosting company uses php as a cgi script with no mod_php, and I'm trying to mirror that at home. That's how I know it's possible.
>How-To-Repeat:
1. Here's my test script test.php3 (only I have opening and closing HTML and BODY tags)...

#!/usr/local/bin/apache
<php? 
echo "test"; 
?>

2. In srm.conf set:
AddType cgi-script .php3

3. Put the above script in your cgi-bin directory five it execute permissions and hit it with your browser.
>Fix:
I know it's possible to use this type of setup, but I have no idea why I'm getting a SEGINT, so not sure how to fix it...
