I work on software that goes to space. I believe we and NASA use the MISRA coding standard, which is effectively this but taken to extremes. If you actually want to create safety critical code I would recommend that you familiarize yourself with the MISRA ruleset and DO-178B.
If anyone is looking into this sort of stuff, you can check out the relatively new DO-178C as well, which adds some more details about tool qualification, formal methods, and model-based development. Signed, your friendly neighbourhood aerospace systems engineer.
Gerard Holzmann is the main author of the formal software verification tool "spin" as well as the owner of spinroot.com. I took a class on formal verification under him at Caltech.
As an anecdote, spin was used in Plan 9 to validate the kernel scheduler and the IL network protocol. It was also used to validate a very early version of the Go scheduler.
I work for your friendly Aviation megacorp producing avionics-related widgets. We are currently transitioning to DO-178C. Fun anecdote: I took a training class on Peach Fuzzer last year & got to hear people from MS, Mozilla, etc. talk about the testing they do on their software. I asked them if they ever had to prove things like worst-case execution time, worst-case stack utilization, perform MC/DC analysis, perform source-to-object analysis, etc., etc. They did not ... and that, my friends, is why avionics software is so damned expensive compared to other software :)
EDIT: And to those of you debating whether all of these rules are necessary and good -- they are; however, they are a subset. We use an internal coding standard that resembles MISRA C but does have some modifications. The only rule of his that we don't do nearly the same way is the 60 line limit. We use code complexity metrics rather than a strict line limit, but it's the same idea.
