internalAstError with complex "using"

[Andrey Alekseenko]

The following code is happily accepted by g++-10 and clang++-15, yet cannot be parsed by cppcheck.

It seems that float_ptr(b.data()) is interpreted as float * (b.data()), which is indeed incorrect, because float_ptr should be treated as a single token. Rewriting the offending statement as (float_ptr)(b.data()) solves the problem.

struct B {
  float *data() const;
};

namespace n {
bool N(float *v);
}

bool c(B &b) {
  using float_ptr = float *;
  return n::N(float_ptr(b.data()));
}

$ ./bin/cppcheck internalAstError.cpp 
Checking internalAstError.cpp ...
internalAstError.cpp:11:25: error: Syntax Error: AST broken, 'b' doesn't have a parent. [internalAstError]
  return n::N(float_ptr(b.data()));
