Re: Getting IMSP segfaults when accessing LDAP

Rob,

Took a while to figure out what to set so that core could get dumped. I
think this is what you're asking for:

I installed Cyrus IMSP server version 1.7b on a RH AS3 server and
configured it with LDAP to use our LDAP server as the backend for
the global addressbook.  I am using the dfault distro libs for LDAP,
and imsp builds okay except I get a bunch of "warning: assignment
makes pointer from integer without a cast" errors when compiling
abook_ldap.c.  The compile nevertheless succeeds.  But when the
server tries to access LDAP to to a search, the process terminates
with a segmention fault.  I don't find any special instructions in
notes/Build-instructions for LDAP, and I followed the instructions
in notes/Setup-instructions to the letter.  Is there something else
I need to do?

Also, I did not include the strace (that's how I know it dies on a
seg fault) because it's quite long, but I can post it if it would be
helpful.


If you can post the backtrace from the coredump, that'd be most
helpful actually.
