Hi, I'm having a problem with DBD::Informix when using it's functions via a 'goto &$sub' mechanism.
My program is a CGI script in perl, which provides web-access to a database
in Informix.
The problem happens in the situation when the program dies from a
'HandleError' handler, assigned to a DBD::Informix database handle.
After the raised error is catched in the calling code,
perl internal data structures seem to be in some inconsistent state
and further actions may lead to a SIGBUS, depending on performed
actions.
The problem appears only if the corresponding DBD::Informix method,
which enables the 'HandleError' handler, is called via a 'goto &$sub'
mechanism.
The problem originally showed with perl 5.8.5 and DBD::Informix
version 2003.04.
But after moving to perl 5.8.6 and DBD::Informix 2005.01 the problem
didn't eliminate.
I opened a ticket on this case in perlbug, but they addressed me to
the DBD::Informix oriented mailing list, so I hope someone here can
reveal the source of the problem.
Or at least help me to find an appropriate place to address with this
problem.
I made a simple test case, reproducing the situation (test.pl in the
attachment).
It works for me on my solaris8 both under perl 5.8.6 and 5.8.5 and with both
DBD::Informix 2003.04 and 2005.01.
In the end of the message goes the output of perlbug -d, just in case.
Best regards,
