Subject: Call _exit() instead of exit() if exec*() fails
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=4418939dd9f3a7b3cfd3071234ed18ae86538f2a;p=st.git

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.
