stderr problem?????

Has anyone ever encountered the following when using 4.2?
fprintf's to stderr simply print nothing.
Tracing the problem with sdb/dbx shows that, indeed, the control 
passes thru the statement. Setting breakpoints at write, however,
seem to fail, as it doesn't stop. Checking fd 2 reveals that it is 
still open. This problem does not happen on EVERY different program
that uses stderr, mind you, but it does seem to consistently happen
to particular program(s). A version of this program which runs on
the 68000 does indeed produce the desired output. I am told that the
drivers/stdio/etc are different for the 68K (ie from older versions
of UNIX).
Oh well, I just thought I'd see if anyone else had witnessed 
similar behavior.

Responses by E-mail, if you wish.

Thanks.
