[internalAstError] on nested lambda passed as argument

[Stefan van Kessel]

I get an internal AST error with this nested lambda passed to a function.

struct Foo
{
  char ch{};
};

void takesFunc(auto f){}

int main()
{
    takesFunc([func=[](Foo i){ return i.ch;}]{});
}

test.cpp:10:39: error: Syntax Error: AST broken, 'i' doesn't have a parent. [internalAstError]
    takesFunc([func=[](Foo i){ return i.ch;}]{});

[CHR]
