hi,
i tried to run php4-head + ZE2 but both CLI and apache(1.3)-sapi
segfault for me.
the steps i did were:
cvs co php4
cd php4
mv Zend ZE1
cvs co -d Zend ZendEngine2
./cvsclean
./buildconf
'./configure' \
'--prefix=/usr/local/php4' \
'--with-apxs=/usr/local/apache/bin/apxs' \
'--disable-overload' \
'--enable-debug' \
"$@"
here's the backtrace:
Starting program: /usr/local/php4/bin/php
Program received signal SIGSEGV, Segmentation fault.

it segfaults due to null-pointer dereference:
EG(objects_store).free_list_head =
EG(objects_store).object_buckets[handle].bucket.free_list.next;
^^^^^^^^^^^^^
(gdb) print executor_globals.objects_store
$1 = {object_buckets = 0x0, top = 0, size = 0, free_list_head = 0}
^^^^^^^^
objects_store is not initialized...
any idea whats going on?
