Bug Type: Reproducible crash
Operating System: Linux x86_64
PHP Version: 5.3.0
New Comment:
After some debugging, I came to the conclusion that it crashes because
of an exception being thrown inside a spl_register_autoload()'ed
userland method.
Here's the bt:

Description:
------------
PHP 5.3.0 crashes when a class is implementing an interface declared in
another namespace
Reproduce code:
---------------
Hi
I am sorry, I was unable to isolate the bug and create a PoC.
However the code (which is rather small) can be found at
svn://yet-another-project.com/projects/yap.
Rev 1. is working, but the crashing code is commented out, Rev.2
crashes when issuing /trunk/tests/runtests.sh.
The tests were written with PHPUnit 3.4.1 in mind.
The error message when running the testsuite through /usr/bin/phpunit
is:
./runtests.sh: line 3: 16512 Segmentation fault phpunit
--bootstrap bootstrap.php --configuration phpunit.xml testunit/
But when issuing /usr/bin/php /usr/bin/phpunit --bootstrap
bootstrap.php --configuration phpunit.xml testunit/ I only get:
Segmentation fault
See the diff between r1 and r2.
