Hello, as I could read in the docu (https://gcc.gnu.org/wiki/SplitStacks) it is possible to call code of a library, which was not compiled with split-stack support, from an application which uses split-stacks. I'm wondering if it might be possible that the library can consume too much stack or does the linker always ensure that enough stack space is available. (Example: an app with split-stack support call a recursive descent parser from a library) thx, Oliver
