What did you do?

This used to work (in 1.13, I think) but fails in 1.14.4:

> go.exe build -tags api -trimpath  -o ..\presstige_api.exe .
can't load package: package -o is not in GOROOT (c:\go\src\-o)
can't load package: package ../presstige_api.exe: cannot find package "." in:
        C:\Users\kjk\src\presstige\presstige_api.exe

Note: If I do go build -o ... it works.

Maybe putting -o option at end was never supposed to work but it is a regression.

@seankhliao it looks like the report does have packages, the last . there.

I can only reproduce this on Linux if I add an explicit empty-string argument to the -trimpath flag.

example.com$ go build -tags api -trimpath  -o ..\whatever.exe .

example.com$ go build -tags api -trimpath '' -o ..\whatever.exe .
go: finding module for package ..whatever.exe
package -o is not in GOROOT (/usr/local/google/home/bcmills/sdk/gotip/src/-o)
malformed module path "..whatever.exe": leading dot in path element

@kjk, does this still reproduce for you if you remove the doubled space after the -trimpath flag?

Timed out in state WaitingForInfo. Closing.
