Preloading will try to evaluate class constants during compilation, but evaluated FCCs are objects, which can not be persisted. Apply the same fix as for enums: Fail evaluation when compiling. Preloading will also reset CG(map_ptr_last) after compilation, which results in collisions if map ptrs were allocated during compilation. Move the ZEND_MAP_PTR_NEW() to the persist phase, as a shared map ptr is not necessary before that.

There was a problem hiding this comment.
I reviewed the PR excluding the first two commits. The tests LGTM. For the implementation, I didn't see obvious issues (except formatting nits), but I'm not fully comfortable approving the C changes.
… of the declaring opline itself This makes the API compatible with creating partials from AST: We can pass &ast->lineno to zend_partial_create()
The declaring op_array is used for multiple purposes: * Generating a PFA name * Finding the filename * Finding whether op_array is cached, and therefore whether the PFA should be cached too However it's not available when evaluating a PFA AST. Remove the declaring_op_array argument, and pass the relevant information directly: * Generate the PFA name at compile time, pass it as argument to zend_partial_create() * Pass the filename and a cacheable flag as argument to zend_partial_create()
