Bug description: system() forces Content-type header output
Description:
------------
Calling the system() function forces the standard Content-type: text/html
header output, even when output buffering is on. This behaviour is unlike
other output commands such as print, which suppress the "automatic" headers
until the output buffer is flushed.
Note that replacing system() with print() in the sample code works as
expected.
Reproduce code:
---------------
<?php
ob_start();
chdir("/");
system("ls");
ob_end_clean();
header("Content-type: text/plain");
print "Hello World.";
?>
Expected result:
----------------
Content-type: text/plain
Hello World.
Actual result:
--------------
Content-type: text/html
Warning: Cannot modify header information - headers already sent...
Hello World.
