If you can produce a small test case, then I can pass it along to
the <br>
binutils group to track .<br>
<br>
Does this happen on GNU/Linux? That would help get attention :)<br>

<div>The last three lines are incorrect. </div>
<div>Look at "rtems_filesystem_table", for instance. It is
expected to be allocated in the source that defines
CONFIGURE_INIT, since it is in confdefs.h, however 'nm'
thinks it is in _isatty.c, line 21 (!!!!).</div>

<div>Can anyone confirm this strange behavior?</div>
