Perhaps this is corrected bug. My original point of view (when I first met this bug): a mistake in reflection for classes that used traits). I removed comment in trait and all successful worked (RC1 or 2, i don't remember). The remainder of the comments for this report are too long.

Yes. Finally recreated it.
Small example with dependencies (zf, doctrine, e.t.c) on github.com:
g...@github.com:alurin/zend-bug.git
Files:
- Example/IdentityTrait.php - trait, add id field
- Example/Temp.php - entity, used IdentityTrait
- library/ - vendors libraries (submodules)
- bootstrap.php - setup doctrine
- script.php - Console interface for doctrine (if update or create data
scheme).
- index.php - Test example
$ php script.php orm:schema-tool:create
ATTENTION: This operation should not be executed in a production environment.
Creating database schema...
Database schema created successfully!

zend_opcode.c:295 is zend_hash_destroy(&ce->function_table);
I don't see why the function table would be problematic, but I will try to look
into it today.

Description:
Hello.
>From first build (RC1), on my computer PHP 5.4 (all RC and last SVN version)
>mysteriously crushed on clean up phase, if used trait. It not reproduces with
>small scripts, only if application has all havy libraries: Doctrine2, Zend
>Framework 2 and many others.
It not serious error, if use application from console of open page in Firefox,
but Chrome often interrupts drawing of content.
Traits has attributes, abstract or static methods.
