So now I reduced my kernel .config that crashes the Go test down to the point where it boots in 1s and doesn't even support PCI. Build the kernel with GCC 6.4.0, Go crashes. 5.4.0, no crash. But I also have *another* full .config that doesn't crash with 6.4.0. The plot thickens.

Now trying to slim down the no-crash .config so I can ultimately diff it and hopefully find the option that makes the difference. And then hope that tells me something useful about the root cause of the crashes.

Ding ding ding it's CONFIG_OPTIMIZE_INLINING, which points back to the compiler. And now I need to figure out which of these function inlining differences is the culprit. https://mrcn.st/p/vxuE2yH4
