Command line output

The version I was able to use was 9.2 i.e. not 9.1 as in the initial report.

The segment trap that was problematic to me was in event-loop.cc. It had
correcly detected that I could not use poll so was attempting to use select.
Unfortunatly macros FD_SET, FD_CLR and FD_ISSET access data outside the data
structure if the file descriptor is NOT less than FD_SETSIZE. The root cause is
that the commercially modified linux kernel that I was attempting to use
encrypts file descriptors, so I was lucky that the encryption did not make the
file descryptor too large on the old version. As stated in earlier comments my
useage is unusual so I would understanf if this was closed, as invalid, without
update for protection against the segment trap.

However, once the segment trap was fixed (by updating glibc so FD_SETSIZE was
larger than the standard value), I did get a warning (see attachment). The
warning is not present in the old version. On "bare metal" build, only built in
conversions are available in iconv i.e. UTF-32BE & UTF-32LE are not available.
However UCS-4BE & UCS-4LE are available. My reading of the 2 sets of
specifications are that they are equivelent. I would alsounderstand if this was
closed with no action on this issue.
