Cannot reproduce with gcc-4.8.3. It could be gcc-4.9 problem.

x86_64-pc-linux-gnu-4.8.3 works

x86_64-pc-linux-gnu-4.9.0 this bug report.
Comment 3 Peter Asplund 2014-10-20 15:01:54 UTC
They seem to be aware of the issue upstream.

Comment 4 Anthony Basile gentoo-dev 2015-01-17 16:09:16 UTC
This may be fixed in 4.9.2 because they fixed some c++ inline optimizations.  Can someone test this for me.

Just checked - it compiles ok with gcc-4.9.2

Thanks.  I'm pretty sure it was the extra work they did on inline optimization stuff.

Reopen if this is still an issue.
