Bug Type: Reproducible crash

New Comment:
i do not have the time or the expertise to compile php with debug
options.
the segfault happends in PEAR.php (PEAR 1.3.5) line 863
eval('$e = new Exception($this->message, $this->code);$e->PEAR_Error =
$this;throw($e);');
it appears that $e->PEAR_Error = $this causes the segfault.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

here is a test case to trigger the segfault :
you need PEAR, DB, DB_Dataobject:
test.php

$options = &PEAR::getStaticProperty($class,

}
$options =
&PEAR::getStaticProperty('DB_DataObject','options');
$options['class_prefix'] = '';
$options['persistent'] = true;
class Test extends DB_Dataobject

public $__table = 'test';
}
$dao = new Test();
try {
$dao->field1 = 'test';
$dao->insert();
}
catch (Exception $e)

var_dump($e);

New Comment:
you have the expertise to do so, i don't. don't get me wrong i have
spent a considerable amount of time trying to find the bug, i can't do
much more.
i have enough trouble explaining my boss why php crashes as it is
supposed to be production ready.

And we don't have time to come up with simple reproducing scripts
either.
