Fixed In Version:	httpd-2.4.6-23.el7	Doc Type:	Bug Fix
Doc Text:	Cause: There was a race-condition in signals handling when httpd was running on foreground and user hit ctrl+c (sent SIGINT to httpd processes). Consequence: In that case, SIGINT was sent to all children followed by SIGTERM from the main process, which interrupted the SIGINT handler and lead to hanging process or crash. Fix: The problem has been fixed by ignoring the SIGINT signals in the child processes. Result: Httpd does not hang or crash in the mentioned situation.	Story Points:	---

I reproduced the issue in Docker (inside a container to be precise), which is shipped only for x86_64 architecture if I am not mistaken. I have not been able to reproduce it anywhere else. Did you encounter the invalid pointer error in other environments too, Jeremy?
