When I compile texinfo-7.1 in such a way that is uses the obstack facility from glibc (via 'gl_cv_func_obstack=yes ../configure ...'), I see the same bus error as in a build where the obstack facility comes from gnulib. Therefore, if it is a bug in gnulib, it is also a bug in glibc. But since obstack_alignment_mask is explicitly documented [1] as a means to change the alignment, I wonder whether it is a bug at all? [1] also says: "By default, this boundary is aligned so that the object can hold any type of data." Needs to be investigated in more depth...
