Subject: Call _exit() instead of exit() if exec*() fails
X-Git-Url: https://git.xinqibao.xyz/st.git/commitdiff_plain/4418939dd9f3a7b3cfd3071234ed18ae86538f2a?ds=sidebyside;hp=4418939dd9f3a7b3cfd3071234ed18ae86538f2a

Call _exit() instead of exit() if exec*() fails

exit() will also unwind the atexit() functions.  This is bad
because if exec*() fails the process is in an inconsistent state.
