Hi Jonas,
I get the follwing warning/error when compiling this commit with clang 3.6:
../tools/clang/tools/extra/clang-tidy/modernize/DeprecatedIosBaseAliasesCheck.cpp:21:5:
error: suggest braces around initialization of subobject
[-Werror,-Wmissing-braces]
"::std::ios_base::io_state", "::std::ios_base::open_mode",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
It looks like r343916 tried to fix it (but failed? and was reverted) so
I suppose I'm not alone seeing it.
Regards,
Mikael
