MinGW exes with DWARF debug info - "cannot locate debugging symbols"

I'm trying to profile a Windows application built with MinGW with DWARF debug information. About a year ago VTune used to correctly load all debug information and show function names; now it fails to load any debug symbols:

Here's the repro - whole set of profiled binaries + two last profiling results.

I'm using the 2017 Update 4 version, and I had the same issue with Update 1. Both gdb and lldb load debug information from the attached binaries correctly.

Thanks
