I compiled a simple ksh shell script with shc (it does not matter which options are used or what the shell script actually does, the result is the same).

./a.out

shll=main
argc=1
argv[0]=./a.out
argv[1]=<null>
getenv(xffffffe4ac74559f)=<null>
shll=/bin/ksh
argc=4
argv[0]=./a.out
argv[1]=-c
argv[2]=exec '*23612*./a.out' "$@"
argv[3]=./a.out
argv[4]=<null>
./a.out: exec: *23612*./a.out: not found

The ksh environment has a strange entry for $_

env

_=*23612*/bin/env
DBPATH=/cms/db/inf
DB_LOCALE=en_us.utf8
G_BROKEN_FILENAMES=1
HISTCONTROL=ignoredups
HISTSIZE=1000
HOME=/root
...

The problem is in the xsh function and here is how I fixed it temporarily:

        //char * me = getenv("_");
        //if (me == NULL) { me = argv[0]; }
        char * me = argv[0];

I am sure there is a better way to fix this permanently.

Fixed in 3.9.3a4
