alt Hacker NewsThe price you pay for GCC nested (local) functions is an executable stack with 'trampolines'.
I'm a fan of nested functions but don't think the executable stack hack is worth it, and using a 'display' is a better solution.

You misunderstood my comment. GNU local function syntax, C++ [&] lambda behavior (i.e., a hidden struct).
