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:

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.

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.

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

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.
