I've often seen the type of behavior you describe when using two
machines one of which NFS mounts a partition from the other (say A
mounts Bs /usr/foo). On B I compile something in /usr/foo, then on A I
try to run it. Sometimes this results in odd behavior for example I've
run things four times in a row getting results of segv, bus error,
trap, and works fine. Sometimes it just continues to act strangely. On
a more stable NFS, usually it lets you know when this is a problem,
but not all NFS implementations are this good.
