Program received signal SIGSEGV, Segmentation fault.

As of 5.3 the segfault was fixed for infinite recursive calls.
Now we get:
"Fatal error: Allowed memory size of 134217728 bytes exhausted at /home/felipe/dev/php5/Zend/zend_execute.h:157 (tried to allocate 261900 bytes)"

but in 5.2 it's expected.


Thanks.
