<br>
the first frames of the backtrace don't have the symbol
table, do have other core files from where you can extract
the bt full?<br>
<br>
Also, 4.2.3 is old in its series, newer versions in branch
4.2 were released. Can you update the latest version in
branch 4.2 and reproduce again? That will rule out is not
a side effect of an issue fixed after 4.2.3. You don't
need to change anything in config or database, just grab
the latest sources from branch 4.3 and install over the
old binaries.<br>
<br>
Cheers,<br>
Daniel
