If you’ve spent much time developing with Mingw-w64 you’ve likely seen the symbol ___chkstk_ms, perhaps in an error message. It’s a little piece of runtime provided by GCC via libgcc which ensures enough of the stack is committed for the caller’s stack frame. The “function” uses a custom ABI and is implemented in assembly. So is the subject of this article, a slightly improved implementation soon to be included in w64devkit as libchkstk (-lchkstk).
