--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
The C++ gimplify langhook gimplifies the gimplifier generated
vol.1 = b.fields
as
vol.1, b.fields;
so it isn't a manifestation of the issue but a fallout of the attempt to
fix it in the C++ gimplifier... it drops the assignment but leaves the
load from the volatile in place (as side-effect to be preserved?). But
then we gimplify that again ... producing vol.2 = b.fields ... and on we go.
