Internal inconsistency in tracking vforks

(S) A warning peculiar to VMS. Perl keeps track of the number of times you've called fork and exec, to determine whether the current call to exec should affect the current script or a subprocess (see exec LIST in perlvms). Somehow, this count has become scrambled, so Perl is making a guess and treating this exec as a request to terminate the Perl script and execute the specified command.
