Bug ID: 70163
Summary: C++ DR 257 constructor forward to virtual base class's
constructor in an abstract class required
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ethouris at gmail dot com
Target Milestone: ---
Sorry if this already passed through somehow, but there was no trace of this
problem so far in gcc bugzilla and I found it in version 4.9.0.
The problem can be described in short as: The constructor forwarder to the base
class's constructor shouldn't be required, if the current class is abstract and
the base class is virtual.
This is completely described as C++ DR 257:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#257
So, it's still working with this defect in gcc 4.9.0, also when compiling in
C++11 mode. May happen that this is already fixed in some later version of gcc,
then please leave appropriate information here.The clang++ compiler has this
problem fixed.
