[Sab] PHP/Sablotron random segfaults (fwd)

fyi and such... -Sterling ---------- Forwarded message ---------- Date: Wed, 10 Oct 2001 13:40:45 +0200 From: Petr Cimprich <petr@gingerall.cz> Reply-To: sablist@gingerall.cz To: Ruud van den Brink <ruud@stress.utwente.nl> Cc: sablist <sablist@gingerall.cz>, Sterling Hughes <sterling@designmultimedia.com> Subject: [Sab] PHP/Sablotron random segfaults This note may be important for those of you experiencing the strange instability of Apache/PHP/Sablotron. We have a (strong) feeling that this problem may be related to expat_lite library which is linked statically to Apache by default. This old library (based on expat 1.2) exports the same symbols as expat 1.9x. Therefore, when you use a software linking expat 1.9x dynamically (as Sablotron does) via Apache, there may be conflicts resulting in random-like segfaults. To avoid this problem, you have to disable expat_lite, (rename src/lib/expat-lite) and recompile Apache. This problem applies to all architectures using expat through Apache (e.g. Charlie, AxKit), but we didn't realize it must be the same for PHP/Sablotron as well. According to Matt's message posted to perl-xml recently, Apache developers will provide a new option (RULE_EXPAT) in the next 1.3.x version to disable expat_lite in a more convenient way. Please, let us know, if this helps.
