>Description:

union mount:
<below>:/u1/usr-local/generic on /usr/local type union

after running /usr/local/bin/cvs for a while, I replace it.
/usr/local/bin/cvs now core dumps, although
/u1/usr-local/generic/bin/cvs does not.  By all indications (sum, ls
-li, etc.) they are the same file.  Eventually, /usr/local/bin/cvs
stops core dumping.

it would seem something is being cached incorrectly.

>How-To-Repeat:

I don't have another different cvs around to try to replicate this.
