Nested functions are causing a lot of problems: the stack must be executable and GCC at Mac OS X still doesn't support them correctly.
The nested functions can be replaced by declaring all local variables in a struct. Nested functions get a pointer to the struct of their lexical scope. A struct might need to have a pointer a struct of its own lexical outer scope. As an alternative, nested functions could be given pointers to structs for all outer lexical scopes.

The development of the new compilation scheme has been finished in revision 15511; the build of the development branch was succesful.
Improvement
Closed
Blocker
Replace GCC nested functions by stack-allocated closures as structs
