--- Comment #7 from David Binderman <dcb314 at hotmail dot com> ---
I am not sure this is fixed. Attached code, when
compiled by 20140817, with flags -std=gnu++11 -O2,
does the following

$ ../results/bin/gcc -c -std=gnu++11 -O2 bug161.cc
listformatter.cpp: In member function ‘icu_53::UnicodeString&
icu_53::ListFormatter::format(const icu_53::UnicodeString*, int32_t,
icu_53::UnicodeString&, int32_t, int32_t&, UErrorCode&) const’:
