Interesting question. The number 104 appears to date back to the first implementation of split stacks in https://go.googlesource.com/go/+/b987f7a757f53f460973622a36eebb696f9b5060. That change introduces a 104 byte stack guard, and I believe that that stack guard has been carried forward over the years. I don't really know whether it still makes any sense today. Probably it doesn't. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
