 New Comment:

This didn't happen with 5.6.2, but I'm uncertain of which version introduced the change.

Note that /usr/bin/php-cgi is SAPI cgi-fcgi.
was compiled with --disable-cli and --enable-cgi.

If I use #!/usr/bin/php in script.php (CLI SAPI), it doesn't hang.

Description:
------------
My lighttpd server uses fastcgi to run php code.

The php code starts an external program that happens to be a standalone php script (shebang: #!/usr/bin/php-cgi).

The script hangs when started from a php-fpm process manager, but works fine when started from a php-cgi "process manager".

Just to clarify, the process that hangs is the php-cgi which is interpreting the standalone script.  If I replace this with a shellscript, everything works fine.

Test script:
---------------
test.php:
<?
header("Content-type: text/plain");
echo "Starting\n";
system("/var/www/htdocs/script.php");
echo "Finished\n";
?>

script.php:
#!/usr/bin/php-cgi -q
<?
echo "Hello world!\n";
?>


Expected result:
----------------
No hangs.
