'exec' produced internal code output instead of normal

[Alex fxmbsw7 Ratchev]

i have no example to write here as this was past long

the story was, i was coding a file server daemon, with socat, and i figured
to use exec why not more exact more efficient

but using it resulted sometimes output of code of the script in the output
of the files
removing exec made it work normally as supposed

any known issue there ?
