---------------------------------------------------------------------- (0005176) zackw (reporter) - 2020-12-15 15:53 https://austingroupbugs.net/view.php?id=1435#c5176 ---------------------------------------------------------------------- If you would prefer a more practical rationale for the proposed change, consider a program (a test suite driver, for instance) that wants to execute binaries that may have been cross-compiled and therefore may not be executable on the system where it's running, and distinguish ENOEXEC-type failure from other forms of failure. It runs on a wide variety of systems and therefore cannot rely on any binary-rejection heuristic being implemented by the shell. The only alternative is to avoid using execlp and execvp, but this means reimplementing PATH search by hand, and depending on the implementation language, it may not even be possible. (For instance, the Perl interpreter *only* exposes execvp and system to Perl programs.)
