I'll annotate the error message a bit for clarification:
> Building packages and commands for host, linux/amd64.
The failure occurred while building all of go for linux, on linux.
> # cmd/vendor/github.com/google/pprof/third_party/d3
This output line reports which package was being built when the failure
occurred.
> unexpected fault address 0x607c60
> fatal error: fault
> [signal SIGBUS: bus error code=0x2 addr=0x607c60 pc=0x607c60]
There was a memory fault related to address 0x607c60 which is the same
as the program counter, suggesting the fault was a failure to fetch
the instruction at that address.

The go runtime traceback suggests that the running binary is the go compiler,
which is being executed from the v9fs file system on the Plan 9 server.
The pc value 0x607c60 is within the text segment of the program, so I'm
guessing there was some problem fetching the page, which the linux kernel
reports as a "bus error" (a generic term for "something went wrong related
to memory").
There's plenty of disk space on the server.
