alt Hacker NewsAnother canard, unfortunately. "Segfault" is simply Go's reporting convention for things like nil pointer hits. "Segfaults" are not, in fact, part of the definition for memory safety or a threshold condition for it. All due respect to Ralf's Ramblings, but I'm going to rest my case with the Prossimo page on memorysafety.org that I just posted. This isn't a real debate.

Blatantly false. From Ralf’s post:
> panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x2a pc=0x468863]
The panic address is 42, a value being mutated, not a nil pointer. You could easily imagine this address pointing to a legal but unintended memory address resulting in a read or write of unintended memory.
