+ // "[libcxxabi] Insert padding in __cxa_exception struct for compatibility". The layout of the
+ // start of __cxa_exception is
+ //
+ // [8 byte void *reserve]
+ // 8 byte size_t referenceCount
+ //
+ // where the (bad, hacky) assumption is that reserve (if present) is null
+ // (__cxa_allocate_exception in at least LLVM 11 zero-fills the object, and nothing actively
+ // sets reserve) while referenceCount is non-null (__cxa_throw sets it to 1, and
+ // __cxa_decrement_exception_refcount destroys the exception as soon as it drops to 0; for a
+ // __cxa_dependent_exception, the referenceCount member is rather
+ //
+ // 8 byte void* primaryException
+ //
+ // but which also will always be set to a non-null value in __cxa_rethrow_primary_exception).
+ // As described in the definition of __cxa_exception
+ // (bridges/source/cpp_uno/gcc3_macosx_x86-64/share.hxx), this hack (together with the "#if 0"
+ // there) can be dropped once we can be sure that we only run against new libcxxabi that has the
