Comment 1:

Well, I can reproduce this, but it's slow to reproduce.
How can I iterate quicker?
Right now I have to:
src$ export CGO_ENABLED=0
src$ ./all.bash
But if I:
src$ cd pkg/net/http
src$ gotest -test.v
... it passes.
Explain the new build world to me?
I'll try to fix it anyway, but doing all.bash between tries isn't fun.

Comment 2:

This was happening to me even before the new build tool,
I just never reported it.  It's a nil pointer deref in the x509 code.
Maybe it only happens with -test.short?
