Thanks for the information. Unfortunately, when I try:
// This part of the extension is in a function that may well be called
// several thousand times from a PHP script.
SEPARATE_ZVAL(&Arr);
array_init(Arr);
The second time through, the httpd process segfaults and dies.
Apparently, I can't just blindly do the separate_zval and array init. I have tried several combinations using the ZVAL_IS_NULL and Z_TYPE_P() == IS_ARRAY beforehand, but I'm just not getting it.
