Subject: replace exit(3) by _exit(2) in signal handler sigchld()
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=d6ea0a1a61853dd892029a7126e7fdb70c371878;hp=d6ea0a1a61853dd892029a7126e7fdb70c371878;p=st.git

replace exit(3) by _exit(2) in signal handler sigchld()

exit(3) is not async-signal-safe but, _exit(2) is.
This change prevents st to crash and dump core.
