Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
----------
This testcase was mechanically derived from preprocessed source. As best as I
can tell the original __gthrw_pthread_once comes from
c++/5.0.0/x86_64-unknown-linux-gnu/bits/gthr-default.h., in case that matters.
The testcase is accepted by GCC 4.8 and 4.9.
