Comment:
I take issue with your assessment, and am closing this as "won't fix" — not
that we could fix it anyway, because it is not our bug! My reasoning goes as
follows:—
1. Microsoft's dumpbin tool is hardly an effective yardstick for determination
of the validity of PE-COFF executables.
2. By your own admission, the git.exe about which you complain, can be loaded
and executed successfully by Windows, and Microsoft's windbg can parse it;
that, for me, is a more effective validation yardstick.
3. This git.exe is a third party product, which we neither distribute, nor
maintain; furthermore, there is no evidence that our tools play any part in
its creation — on the contrary, there is strong evidence that they do not!
On this basis, I conclude that it is not git.exe which is at fault, but rather
dumpbin which is defective; only Microsoft can fix that.

Ticket details:
When using git.exe on Windows as part of the Chromium project I tried to obtain
details about the debug information (PDB files) associated with git.exe by
using Visual Studio's dumpbin. This failed due to invalid fields in the git.exe
PE file. Details can be found in this Visual Studio bug:
https://developercommunity.visualstudio.com/content/problem/386596/
dumpbin-fails-on-gitexe-for-windows.html
Although Microsoft may update dumpbin to work around this bug in the git.exe
binary as created by mingw it would be preferable if mingw would stop creating
invalid PE files.
I obtained git.exe from https://github.com/git-for-windows/git/tree/
v2.19.1.windows.1
