I Tried to create a debug build using go build -gcflags="all=-N -l" -o test .

But it is giving me

# gitlab.com/xyz/repo/pkg/profile
../../pkg/profile/state_mapping.go:8:5: internal compiler error: NewBulk too big: nbit=20196 count=986153 nword=632 size=623248696

Please file a bug report including a short program that triggers the error.

Checked the file, originally it contained static mapping, but after removing all the mappings and making it empty it is showing the same error.

Modified file contents:

package profile

type CountryData struct {
    Country     string
    CountryCode string
}

var StateMapping = map[string][]CountryData{}

Still giving internal compiler error: NewBulk too big... error message when tried to debug the build.

Tried to create a debug build for go service. Wanted to debug the code.
