Fixed in CVS HEAD and PHP_5_0.

Dmitry, if you have time, can you look into these reports with problems
with zend.ze1_compatibility_mode?
Some of them happen with only PHP_5_0 and some with both it and HEAD.
Here's list (this bug excluded):
bug #30332
bug #31828
bug #32080

Not using my php.ini doesn't crash in 5.0.4, 5.0.5dev or 5.1cvs and the
output match the expected.
So investigating my modified settings from the original php.ini-dist,
I've found that ze1_compat generates the problem:
zend.ze1_compatibility_mode = On
(turning it Off does not crash, well, afterall it's php5 only syntax).
The other requested data:
gcc-3.4.1
bison-1.875
glibc-2.3.3
------------------------------------------------------------------------

I still can't reproduce this. I get same result with both HEAD and
PHP_5_0 branches and also with the snapshot.
Does it give same result if you make sure you don't load any php.ini:
sapi/cli/php -n file.php
What bison version do you have installed?
What compiler (and version) ?

With today's CVS (5.1), it does not crash. But the output is:
Output:
i'm called
i'm called
i'm called
i'm called
The __destruct() function is called 4 times.
With php5-STABLE-200504271035 (5.0.5dev):
$ make distclean
$ ./configure \
--prefix=/usr \
--with-config-file-path=/etc/php5 \
--enable-cli \
--disable-cgi \
--disable-pear \
--enable-debug
Still the same output and same crash.
