Fwd: Simple program immediately killed when running on a NFS

[Otacílio]

Dears

I'm trying to compile a simple hello world program on my RPI3. The
program is on a directory mounted using NFS and stored in the amd64
machine. When I compile and try to run the program in the NFS mounted
path it does not work, when I copy the same program to a local dir it
works, and then when I copy the program from the local dir to the NFS dir
it works !?!?!?! Someone can, please, explain it? Look at the historic
program. On this same scenario, my beagleboneblack behaves without mistakes.

root at rpi3:/usr/ports/benchmarks/netperf/work/netperf-2.7.0 # cc -o
conftest conftest.c
root at rpi3:/usr/ports/benchmarks/netperf/work/netperf-2.7.0 # ./conftest

Thanks a lot!
