This is the traceback:

Title:
  gccgo fails to compile tomb.go on arm64

Status in “gcc-4.8” package in Ubuntu:
  New

Bug description:
  Hi, on am2:

  ubuntu at arm64:~/gopath/src/launchpad.net/tomb$ gccgo -g -c -o tomb.o tomb.go
  tomb.go: In function 'tomb.Wait.pN12_go.tomb.Tomb':
  tomb.go:108:1: error: total size of local objects too large
   func (t *Tomb) Wait() error {
   ^
  tomb.go: In function 'tomb.Kill.pN12_go.tomb.Tomb':
  tomb.go:134:1: error: total size of local objects too large
   func (t *Tomb) Kill(reason error) {
   ^

  This is the first error line:
  http://bazaar.launchpad.net/~niemeyer/tomb/trunk/view/head:/tomb.go#L108
  which seems pretty innocuous.

  Will dig (and probably kick upstream) in January.
