 New Comment:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

I was wondering if there was some change in the status of this issue.

Also, I've noticed that even when SIGINT is handled, it will close down
children. I could draw up a program if this appears to be unrelated.

Description:
------------
When a SIGINT is sent via CTRL+C or CTRL+BREAK, the handler is called.
If this handler sends a SIGTERM to other children, the signals are not
received.

SIGINT can be sent via posix_kill() and it work exactly as expected--
This only applies when initiated via a hard break.

SIGTERM will also work perfectly.

Reproduce code:
---------------
http://www.blitzeclipse.com:81/breakhandle.php

Expected result:
----------------
Once the main process, its child, and that child's child are up,
pressing CTRL+C or CTRL+BREAK should cause the first process to
terminate the second process, and the second process should then
terminate the third process.

Actual result:
--------------
When CTRL+C or CTRL+BREAK is pressed, the first process terminates, and
nothing else responds.
