Yep. ulimit reports "unlimited".
Script is intended for METHOD=POST, so I have a "debug" version which
simply outputs a script to set all the environment variables, and a
file containing all the POSTed parameters. The regular version,
when REQUEST_METHOD doesn't exist and "@filename" appears on the
command line, reads and initializes the POST parameters from the
filename specified on the command line. And runs to completion.
If I have its output written to a file, I can read that file in a
browser and see EXACTLY what I expect the script to output. If I
run it as a CGI script, it aborts before 90% of the output appears
(but -- that 90% of the output is generated at the VERY END of the
script's run, after it does all its analysis and builds up a fairly
large N-ary tree in memory, then prints it out as an unordered list
(<ul><li></li><li><ul><li></li><li></li></ul></li><li></li></ul>).
Run that command at a shell prompt after setting all the environment
variables, and it runs to completion.
Run it under GDB (DDD) and same results.
Even run it under strace and it completes OK.
I'd run it under these debuggers all the time, if it didn't
exponentially slow it down.
