--- Comment #4 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
I'm not very picky about having a test for this FWIW, this seems very sensi=
tive
to optimizations and may not survive gcc updates.

As for the fix, just remove the  __attr_access ((__write_only__, 1, 3)), it=
's
incorrect in the context of mbstowcs definition.
