Thank you for reply.
I tried latest snapshot php5-200507211030.
but same error occured.
upper one produces the SIGSEGV. this one
set_error_handler('errorHandler', E_USER_ERROR);
try{
    test();
}catch(Exception $e){
}
restore_error_handler();

Is this caused by my glibc version?
rpm -qa | grep glibc
glibc-32bit-9.2-200412151444
glibc-devel-32bit-9.2-200412202043
glibc-2.3.3-118
glibc-locale-2.3.3-118

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

So which of the two examples produces the SIGSEGV ?
Also, please try latest snapshot, as I can't reproduce it with both
pieces of code you've provided.

Description:
------------
When I using Phing, My testcase with PEAR-SOAP and rdfapi-php had
stopped with segmentation fault.

And I Found that throwing exception in error_handler causes Seg fault.



Reproduce code:
---------------
<?php
set_error_handler('errorHandler', E_USER_ERROR);
try{
    test();
}catch(Exception $e){
}
restore_error_handler();

function test(){
    trigger_error("error", E_USER_ERROR);
}

function errorHandler($errno, $errstr, $errfile, $errline) {
    throw new Exception();
}
?>
-----
no try and catch
<?php
set_error_handler('errorHandler', E_USER_ERROR);
test();
restore_error_handler();

function test(){
    trigger_error("error", E_USER_ERROR);
}

function errorHandler($errno, $errstr, $errfile, $errline) {
    throw new Exception();
}
?>


Expected result:
----------------
nothing

Actual result:
--------------
