Running what you've built when you've added a malicious dependency also causes arbitrary code execution.

Add more and more to a standard library, and you're going to start losing your "works everywhere".

That's a pretty great article. Re. the stack probes, it's not hard to supply your own; Raymond Chen recently did a blog series on stack probes, the entries for amd64 and arm64 are here: amd64: https://devblogs.microsoft

By "system libc" I'm only referring to msvcrt.dll, found in the Windows directory. Quoting Raymond Chen: > At some point, the decision was made to just give up and declare it an operating system DLL, to be used only by ope

Those incompatible runtimes are separated by a linker that doesn't resolve all symbols globally, but rather scoped to the shared object they're expected from. They all coexist happily, and if you're so inclined you could reso

> That only massively compounds the problem. The Windows ecosystem, that manages to deliver built binaries easily & widely, regardless of whether the author has a 1 year old OS or a 15 year old OS, suggests that it's not as big

Targeting an older version of Windows is "set a define so that the system headers don't expose functions that didn't exist on older Windows". You don't need an old toolchain to target old systems, you ask the newer

> Can't be done. The libc is legacy, it can't be changed without breaking everything. It's also mandatory on every operating system other than Linux. Windows explicitly does not want you to link the system libc. You are ex

I'm not sure that's particularly relevant; if I null out bits of the statically linked binary to remove some code paths, they break too.

You don't strictly need to; you can write freestanding C, and use the Linux kernel directly.

Windows loader is part of the system ABI, and programs' libc(s) are loaded by it. One of the ways Windows manages to support multiple libc's is by being careful not to mix allocators; if a system API you call allocates on your beh

insanitybit's point is that "boring" can imply those things, but it can imply other things too. If you have to bring the correct context to make the word make sense, and there's other contexts that could apply that don&#

If you want the library to perform that selection, you also need the "correct" / most efficient implementation to be independent of your workload. I'm not that familiar with SIMD performance characteristics, but I wouldn

I expect it's referring to the newtype pattern; you don't want to accidentally add inches to cm, so if you have to handle both of them a lot, you make a single field struct Inches and one for Cm. For containers, you can do this to

Bugs due to cache state are absurd. In the classical sense of the word. When Bruce Dawson investigated a bug in the Xbox 360 cpu, the offending instructions didn't even need to "execute" in order to crash the system. [0] htt
