--- Comment #8 from Julien Nabet <serval2412 at yahoo.fr> ---
On pc Debian x6-64 with master sources updated today, I could reproduce this.
I noticed that in
/home/julien/lo/libreoffice/connectivity/source/drivers/firebird/ResultSetMetaData.cxx,
connectivity::firebird::OResultSetMetaData::getColumnName, I could already
retrieve "CONSTANT" so I think it seems to come from firebird engine. But
perhaps I'm wrong.
I also noticed the difference between sqlname and aliasname for CONSTANT, eg: 
(gdb) p m_pSqlda->sqlvar[column-1].sqlname
$34 = "CONSTANT", '\000' <repeats 23 times>
(gdb) p m_pSqlda->sqlvar[column-1].aliasname
$35 = "Strasse", '\000' <repeats 24 times>
