           Summary: sljitProtExecAllocator temp file descriptor isn't

          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: bug

         Component: Code

Libraries that open files should make sure the FD is closed on exec, so either
open using O_CLOEXEC, or set FD_CLOEXEC on the FD later.

Here the (temp) file is opened using mkstemp(), so an fcntl(fd, F_SETFD,
FD_CLOEXEC) should be placed immediately afterwards.
