Bug ID: 114740 Summary: i686-linux-gnu-g++ does not interpret floating point literals as double Product: gcc Version: 13.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: gnu.ojxq8 at dralias dot com Target Milestone: --- Starting with i686-linux-gnu-g++-13, including 14, a floating point literal appears to be no longer interpreted as double. i686-linux-gnu-g++-12, and earlier, as well as clang, work fine. Steps to reproduce: $ echo 'int main() { return double(1e-8) == 1e-8; }' > a.cpp $ i686-linux-gnu-g++-13 -std=c++03 test.cpp && ./a.out ; echo $? 0 $ i686-linux-gnu-g++-12 -std=c++03 test.cpp && ./a.out ; echo $? 1
