Converting from initializer list would use explicit constructor Date: Fri, 28 Apr 2023 09:56:13 +0000 [thread overview] Message-ID: <bug-109663-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109663 Bug ID: 109663 Summary: False positive? Converting from initializer list would use explicit constructor Product: gcc Version: 13.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: carlosgalvezp at gmail dot com Target Milestone: --- Created attachment 54950 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54950&action=edit Preprocessed source Hi! We are bumping our GCC installation from 6910cad55ffc330dc9767d2c8e0b66ccfa4134af to cc035c5d8672f87dc8c2756d9f8367903aa72d93 (GCC 13.1 release), and are now getting a handful of errors in this type of code compiling in C++14 mode: #include <Eigen/Dense> int main() { constexpr std::size_t kColumns{4}; constexpr std::size_t kRows{4}; using MyVector = Eigen::Matrix<float, kColumns, 1>; using MyMatrix = Eigen::Matrix<float, kColumns, kRows>; MyMatrix matrix{MyMatrix::Zero()}; MyVector const& my_col{matrix.col(0)}; } Godbolt: https://godbolt.org/z/rx6EY4qbY Preprocessed source attached. I am wondering if this is a False Positive or a real error that should be fixed?
