Thanks Joshua. Those nested functions are toxic.
Nested functions have the obvious effect breaking tools like Clang. But worse, you can't use NX-stacks (-Wl,-z,noexecstack). NX-Stacks and nested functions are mutually exclusive because GCC places a trampoline on the stack. The lack of NX-Stacks could be a security defect and could lead to governance problems.
