What is a right way to build .exe and debug with gdb ?
The version of gdb that ships with MSYS is probably going to
expect debug info in a different format than what dmd puts out on
Windows (I assume it expects DWARF2).
When using -m32(always the default on Windows when invoking dmd
directly), it outputs debug info in an old version of the
CodeView format (which you'll probably need an older version of
WinDbg to work with). Otherwise (-m64, -m32mscoff), it creates a
PDB file usable with the Visual Studio debugger and other
debuggers that understand the PDB format (which is basically a
wrapper for modern CodeView debug info). If there's a Windows
version of gdb that supports CodeView/PDB, I'm unaware of it.
I know some people use Mago:

Some docs on PDB & CodeView:

DMD and debug info on Windows:
