Invalid signature for .pdb files in binary Windows package

The .pdb files from http://master.qt.io/archive/qt/5.5/5.5.0/pdb/pdb-msvc-2013-32.7z DO NOT MATCH the MSVC x32 version of QT 5.5 installed via offline installer from http://download.qt.io/official_releases/qt/5.5/5.5.0/qt-opensource-windows-x86-msvc2013-5.5.0.exe.

Here is the result of match comparison via ChkMatch:

None of the Qt5Cored.pdb versions from every archive in http://master.qt.io/archive/qt/5.5/5.5.0/pdb/ matched. But I was able to match .dll and .pdb files via the -m switch of ChkMatch tool.
Visual Studio 2013 with Update 4 has successfully loaded such corrected .pdb files.

Please, fix this.
