What did you do?

My project use net/http Client to send request via https to server,
build env is windows10 use go build -buildmode=c-shared to build dll and run on windows7 PC.
when windows7 PC local certificate donot have server certificate's Root CA certificate , then return error is tls: failed to verify certificate: x509: certificate signed by unknown author
At this time many request be sent to server, and the progream memory increase fast to 1GB.
I think maybe the http.Client send reqeust via https and No RootCA certificate cause memory leak.

What did you see happen?
