@odeke-em requested issue #34878 to be considered for backport to the next 1.13 minor release.

Thank you for the report @bradleyjkemp!

This a new panic in Go1.13 that stems from the fact that invoking Header.Clone() when Header is nil returns a nil map as we implemented in CL https://go-review.googlesource.com/c/go/+/188022 to solve the inconsistency behavior of Clone as per #33141, but we didn't go through all the call sites to check that the map was nil before assignment.

The code posted up used to work in Go1.12 and before, now fails in Go1.13.
/cc @andybons @bradfitz @FiloSottile for awareness

@gopherbot please backport this issue to Go1.13.

[release-branch.go1.13] net/http: fix Transport panic with nil Reques…
2018d43 
…t.Header

For Go 1.13 we introduced Header.Clone and it returns
nil if a nil Header is cloned. Unfortunately, though,
this exported Header.Clone nil behavior differed from
the old Go 1.12 and earlier internal header clone
behavior which always returned non-nil Headers.
This CL fixes the places where that distinction mattered.

Fixes #34882
