For start, it would be nice to provide some useful information together
or even instead of the long story.

What is the architecture ? Show at least the output of the size(1) on
the final binary. Show exact shell message on the attempt of the binary
run. Show the ktrace/kdump of the start attempt.

As a guess, look at the sysctl kern.maxtsiz and compare it to the text
size reported by the size(1). The same for the initialized data segment
and kern.maxdsiz.
