Workaround for this, try to add
-ldflags="-linkmode=external"
for build.I reproduce this error every time I try debugging a binary with a
-race
argument for go tool in the GoLand IDE.Can confirm this as well on windows 10, go 1.10.3 and gcc 8.1.0 x86_64
For anyone else who ends up here, I’ve used the excellent MinGW compiler collection bundle from @StephanTLavavej for building CGO stuff on Windows for years. It’s great, up-to-date, and it fixed this issue for me.

Having the same issue. @mattn 's workaround did not work for me.
