Type: Bug
Package: Reproducible crash
Operating System: Gentoo Linux
PHP Version: trunk-SVN-2011-10-20 (SVN)

Private report: N
New Comment:
The segfault appears the second time it executes $this->handler-
>sqliteCreateFunction() in the setUp().
If unset() isn't used in tearDown(), then there is no crash.

Description:
------------
PHP 5.4 / trunk segfault while using phpunit.
It only happens with one specific test, however, it looks like that test content
is not relevant at all, emptying its content or putting a
"die" at the end of that test avoid the segfault. It must happen in the phpunit
code after the execution of that test.
Tested using trunk @rev 318251
See the backtrace which is more relevant.
Actual result:
--------------
