So, referenceCount needs to be in any case nuked from struct __cxa_exception.
IMHO, either we define (probably in a different namespace)
struct __cxa_exception_with_refcount
{
_Atomic_word referenceCount;
struct _

I was a bit sloppy in what I wrote before (i.e., in what Matthias turned into

members caused by the addition of referenceCount that

I filed the x86 issue with -mavx as PR 38736. This is a regression and really
needs to be fixed for before the release of 4.4.

There is padding between adjustedPtr and unwindHeader because the latter is
forced to be maximally aligned. Due to the additional member the padding was
reduced. Also, the alignment of _Unwind_Exception depends on -mavx.
