Bug Type: Reproducible crash
Operating System: Linux
PHP Version: 5.0.4
New Comment:
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.

If you configure with --enable-debug (rm config.cache && ./configure +
your options + --enable-debug && make clean && make) does it still
crash? Are you sure you ARE using the latest CVS? (the snapshots might
not be updated again..)

Still works fine here.
Both with HEAD and 5.0.x.

Versions and compile options for the two that crashes for me. In case
it says something for you, if I remove the __destructor() function the
code works good (also you see in the output this function is being
called twice).

For some reason it doesn't crash for me..did you use --enable-debug ?
