--- Comment #6 from Jonathan Wakely ---
This seems different enough to PR 63151 and PR 66617 to warrant it's own PR.
Reduced:
struct VBase { };
class Base
: public virtual VBase
{
protected:
Base(int, int)
{}
};
struct Derived : Base
{
Derived()
:
Base{1, 1}
{}
};
Derived myDerived;
x.cc: In constructor ‘Derived::Derived()’:
x.cc:15:12: error: ‘Base::Base(int, int)’ is protected within this context
Base{1, 1}
^
x.cc:7:2: note: declared protected here
Base(int, int)
^
[Bug c++/66847] Derived class calling protected base ctor using C++11 {brace} init = spurious access denied error
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66847 --- Comment #5 from DB --- Another note is that, as per the other tickets, G++ seems to have multiple possible causes of its confusion with brace-init: * presence of virtual base in class hierarchy * signature of calling class ctor vs base ctor * presence/absence of member variables * possible more...? Hopefully it points at a single cause that can be fixed fairly easily. As currently we have to selectively regress certain parts of our source, to work around G++, and add large comments explaining the inconsistency, which is far from ideal. It's also conceivable that certain situations couldn't be worked around by replacing the bracket type, though thankfully we've not had that yet. Cheers, D.

--- Comment #4 from DB ---
It should be noted that although I have a commented-out {brace} ctor for the
final class in main(), that was just a test; both {brace} and (parenthesis)
init in that context produce the same behaviour. That is: dependent upon the
type of braces used by Derived to call Base ctor.
