I have updated to the latest packages (including those of php5) and the segfault remains. On my system, only the moodle cron script triggers this bug. Other test scripts do not produce this. However, I have not tried with php-postgres included, although that does seem to be needed given that the moodle script accesses a postgresql database. fwiw, these are the packages i could not/did not install in the test chroot. besides the linux-image stuff, the dell stuff, and some local configuration-looking packages, i saw some older packages no longer available in etch. you might want to see what's in those packages, if any of them have shared libraries could you share their contents? I have removed all unnecessary packages and the problem remains. The remaining packages are unrelated and do not show up in the shared library dependency list of the core file produced.

See attached. I vaguely remember seeing this problem when this was a sarge machine as well. As another test, I removed the php5-curl module and now the moodle script runs without problems. So the problem is triggered by the curl module as suspected. One thing to mention is that I'm using Kerberos... and since libcurl links against libkrb5, it might be that libcurl contains Kerberos related bugs... ? However, after adding the debugging libraries, no Kerberos calls appear in the backtrace (see below). Regards, -- Hans (gdb) bt #0 0xf74932f0 in ??

hi hans, i'm still unable to reproduce this problem. can you give me: - your list of installed/configured php extensions (php.ini and conf.d/*.ini) - package versions for libssl*, libcurl*, libssl* and maybe we can take things from there. also, could you check to see if this problem is in the latest version of the php packages? if you're using etch a new version was recently uploaded to testing-proposed-updates that contains security fixes you'll want anyways :) sean signature.asc Description: This is a digitally signed message part
