--- Comment #4 from Jonny Grant <jg at jguk dot org> ---
Also, it is "copy" that is unused uninitialized? (not "temp")
The line carat is also incorrect I believe, it should be header.cpp:10:12 ?
So would be better if it was as follows:
===============================================
$ g++ -O2 -Werror=uninitialized -o header header.cpp
header.cpp: In function ‘void test(info_t)’:
header.cpp:10:12: error: ‘copy.info::registered’ is used uninitialized in this
function [-Werror=uninitialized]
temp = copy;
~~~~~^~~~~~
cc1plus: some warnings being treated as errors
