Hello, everyone,

For Qt builds using Windows ICC got error:

which relate to recently merged Change #225048.

Reproduced for:

  • builds using Windows ICC with Debug configuration,

not reproduced for:

  • builds using Windows ICC with Release configuration,
  • builds using mingw-w64 and MSVC.

Environment:

It was reported on Qt bugtracker (see QTBUG-68751), and Qt Developers believe it's a compiler bug.

 

Best,

Alexander
