trying to build CVS version with ZendEngine2 and use the overload extension.
PHP crashes with a bus error on the call to overload(). it's a hash table
problem, over my head for sure. i can't get this to work at all and wonder
if it's a Darwin(OS X) issue. has anyone else run into this?
this is the compile process:
cvs checkout php4
cd php4
cvs checkout ZendEngine2
then i have to edit ZendEngine2/Zend.m4 to change this line:
fprintf(fp, "%d %d\n", ZEND_MM_ALIGNMENT, zeros);
to add that '\n' char, or else configure fails and ZEND_MM_ALIGNMENT
and ZEND_MM_ALIGNMENT_LOG2 don't get defined correctly - you can see
why i'm thinking this is a platform and/or config problem...
then continuing:
./buildconf --ZendEngine2
mv Zend Zend1.2
mv ZendEngine2 Zend
./configure
make
