The NetBSD headers ship with max_align_t, that is not compatible with the fallback version in libc++. There is no defined a compiler specific symbol in the headers like: - __CLANG_MAX_ALIGN_T_DEFINED - _GCC_MAX_ALIGN_T - __DEFINED_max_align_t Sponsored by <The NetBSD Foundation> Repository: rL LLVM https://reviews.llvm.org/D47814 Files: include/cstddef include/stddef.h Index: include/stddef.h =================================================================== --- include/stddef.h +++ include/stddef.h @@ -54,7 +54,7 @@ // Re-use the compiler's <stddef.h> max_align_t where possible. #if !defined(__CLANG_MAX_ALIGN_T_DEFINED) && !defined(_GCC_MAX_ALIGN_T) && \ - !defined(__DEFINED_max_align_t) + !defined(__DEFINED_max_align_t) && !defined(__NetBSD__) typedef long double max_align_t; #endif Index: include/cstddef =================================================================== --- include/cstddef +++ include/cstddef @@ -50,7 +50,7 @@ using ::size_t; #if defined(__CLANG_MAX_ALIGN_T_DEFINED) || defined(_GCC_MAX_ALIGN_T) || \ - defined(__DEFINED_max_align_t) + defined(__DEFINED_max_align_t) || defined(__NetBSD__) // Re-use the compiler's <stddef.h> max_align_t where possible. using ::max_align_t; #else
