--- Comment #3 from David Edelsohn <dje at gcc dot gnu.org> ---
.good: 0 .fail: 1
width: 50000000 size: 33554432
str_01[0]: 97
oss_01.str()[0]: 32

The string is filled with L'a' (0x97). The stringstream is filled with space
(0x32) and width is not set to 0 although size is non-zero. Assuming that this
is using include/bits/ostream_insert.h:__ostream_insert(), this would seem to
stop before the __out.width(0) statement.
