I reported earlier perl's `make test' reported an error in io.tell, test 3. I've installed patches through #23 now, and the problem is still there. This is Ultrix 1.2. I got mail from Paul DuBois that he had encountered this, but have heard nothing else. I can now report that the same source tests out with no error on Sun 3, v. 3.5. Any help out there?

There is a known bug in Ultrix 1.2 that second and subsequent filbuf()s on
a file at EOF erroneously advance the file pointer by 1. This situation
almost never arises in real code.
I'm not currently planning on fixing this in perl, since it is unlikely to
affect anyone. I suggest that you simply ignore io.tell test 3 (and 12, which
depends on 3). If you're really worried about it, you can always upgrade your
Ultrix. 1/2 :-)

Any attempt to "fix" it in perl would remove some of the flexibility now possible and it's probably not something the will give you a problem in a normal perl program. Can anybody report whether the problem exists in Ultrix 2.[012]? If so, it would be a good idea to write up an SPR.
