--- Comment #8 from Jakub Kulik <jakub.kulik at oracle dot com> --- Sure, this was just a quick first test. That said, GODEBUG is slightly more complex - is there an example of a C code where GODEBUG variables are being used you can point me to (I found only go sources with anything GODEBUG related)? As for the split stack, I will try looking into it and see if it works. Having overhead might solve the issue with no linker support, but it's indeed pretty wasteful (and might break what works currently)...
