execve does not return if the call is successful. I don't see what you
mean here, and there is a contradication with what you are saying
earlier in your message.

fork/execve is fine from an Ada program, even with tasks. I have done
that for years without major problems. Post the code fragment, I cannot
guess more from your message.
