Hmm, this routine was very recently changed by Jason Merrill:
http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00209.html
I don't quite understand that patch, but it definitely changes
the handling of freshly initialized VAR_DECLs in layout_decl from
! DECL_ALIGN (decl) = TYPE_ALIGN (type);
! DECL_USER_ALIGN (decl) = 0;
to
+ DECL_ALIGN (decl) = TYPE_ALIGN (type);
+ DECL_USER_ALIGN (decl) = TYPE_USER_ALIGN (type);
This certainly explains why I haven't seen the problem earlier ...
Bye,
Ulrich
