godoc segfaults #747
Description
Before filing a bug, please check whether it has been fixed since
the latest release: run "hg pull -u" and retry what you did to
reproduce the problem. Thanks.
What steps will reproduce the problem?
I run godoc using the following command line:
godoc -path=/Users/petar/tonika-git/src/pkg -http=:6060
When I navigate to the menu item "Source files" I get a
segfault. This does not happen if I use:
godoc -http=:6060
What is the expected output? What do you see instead?
