This exposed a few underlying issues: 1. is_pod_struct was too strict to allow this. I've relaxed it to require only trivially copyable and standard layout, rather than POD (which additionally requires a trivial constructor, which std::complex violates). 2. format_descriptor<std::complex<T>>::format() returned numpy format strings instead of PEP3118 format strings, but register_dtype feeds format codes of its fields to _dtype_from_pep3118. I've changed it to return PEP3118 format codes. format_descriptor is a public type, so this may be considered an incompatible change. 3. register_structured_dtype tried to be smart about whether to mark fields as unaligned (with ^). However, it's examining the C++ alignment, rather than what numpy (or possibly PEP3118) thinks the alignment should be. For complex values those are different. I've made it mark all fields as ^ unconditionally, which should always be safe even if they are aligned, because we explicitly mark the padding. |
