fix erroneous type inference for static class fields of array type - #1667
Merged
Conversation
A static field's init value is stored in php globals and is reset via hard_reset_var() on every request startup, where memory allocations are forbidden; its constant initializer must therefore have exactly the same C++ type as the field itself (otherwise a converting copy_from() is generated, which allocates memory and crashes)
