Bug Type: Scripting Engine problem
Operating System: GNU/Linux 2.4.20
PHP Version: 4.3.4-dev
New Comment:
I don't know if it's of any help, but i found out that the 4.3.4-dev
version prints out more debug information as the 4.3.3 i initially ([21
Sep 11:21am EDT]) used (if compiled "--with-debug"), so here once again
a debug output:
--- snip ---

Just to be sure, i compiled a new valgrind using
the latest stable version: valgrind-20030725
As far as i can tell, the output is identical...
1) valgrind --run-libc-freeres=yes ;# SEGFAULT
http://farcaster.net/valgrind2-err.log
1) valgrind --run-libc-freeres=no ;# NO SEGFAULT
http://farcaster.net/valgrind2-noerr.log

- valgrind-1.9.6
- PHP (4.3.x-dev) snapshot from Sep 23, 2003 09:30 (as in all of my
latest tests), CLI version

With what PHP version are you getting those valgrind outputs?
And are you using the latest valgrind?

BTW: i don't know if this might help, but here are two
valgrind traces:
1) valgrind --run-libc-freeres=yes ;# SEGFAULT
http://farcaster.net/valgrind-err.log
1) valgrind --run-libc-freeres=no ;# NO SEGFAULT
http://farcaster.net/valgrind-noerr.log

> Please provide a short example script which can be used to reproduce
this.
i'll try- but i fear i'll fast get to a state like [21 Sep 2:50pm EDT]
... isn't there any other way to trace this?
possibly using some kind of memory debugger?
> And don't mix any Zend extensions in this mess, such as debuggers,
optimizers or caches.
I didn't mean to; i was just curious about being possibly
able to figure out what actually led to this problem.
