Bug ID: 110261 Summary: vec.h mentions C++03 requirement for PODs and with respect to unions Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: internal-improvement Severity: normal Priority: P3 Component: middle-end Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- Since GCC is now written in C++11 (since GCC 11, r11-462-g5329b59a2e13dabbe2), the comment in vec.h: As long as we use C++03, we cannot have constructors nor destructors in classes that are stored in unions. */ No longer applies. I have not tested using a non-POD with vec yet but I just wanted to record this here for future reference and for others when some one finally notices this and decides to test it.
