--- Comment #35 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- I'd like to bring back to attention the fact that the code that deducts six from the pc (s390x) in pprof.go is broken regardless of what patches are made to the runtime code. Determining the size of the call instruction is by no means trivial. Other platforms certainly have similar problems with the "pc -= 4". It would be good to solve this at the same time as the "pc--" problem.
