hi,


hi

i just my request never made it back to the OP for more information, so
i'm re-requesting additional information on this bug.

could you verify that this is still a problem with the latest version of
php?  

i still have segfault with libapache-mod-php,php5-common (5.1.6-1).

there were some issues with libdb-linking that may have caused

segfaulting like what you describe.

this makes me suspect even further that this is the problem.  if you're
using nss-db which links against the same symbols and the badly-linked
version of php, i would suspect this.  please try with 5.1.6-4 and let
me know if you still have problems.


thanks,
sean

hi,

i just my request never made it back to the OP for more information, so
i'm re-requesting additional information on this bug.

could you verify that this is still a problem with the latest version of
php?  there were some issues with libdb-linking that may have caused
segfaulting like what you describe.

if i don't hear back soon i'll downgrade the severity as it could
possibly interfere with sid-etch migration of the php packages.  the
release managers may chime in at some point as well.


thanks,
sean
