Hello,
Needs to analyse from our side. Thank you for reporting. But looks like there are can be fast solution with updating compiler flags for mingw. Could you create a ticket in our mug tracker?
Best regards, Commenter-1.
Thank you very much
hi，today I have updated compiler flags for mingw，mingw is x86_64-13.2.0-release-win32-seh-ucrt-rt_v11-rev0。
But the same problem still occurred：
