False positive accessMoved on move capture

[Frank Winklmeier]

Hi,

the following code results in a false positive (tested with 2.15 dev from 2024-07-17):

#include <string>

void foo(std::string bar) {
  auto lambda = [ bar {std::move(bar)} ]() {
    std::string bar2 = std::move(bar);
  };
}

test.cxx:5:34: warning: Access of moved variable 'bar'. [accessMoved]
    std::string bar2 = std::move(bar);
                                 ^
test.cxx:4:24: note: Calling std::move(bar)
  auto lambda = [ bar {std::move(bar)} ]() {
                       ^
test.cxx:5:34: note: Access of moved variable 'bar'.
    std::string bar2 = std::move(bar);
                                 ^

Changing the move capture to the syntax

  auto lambda = [ bar = std::move(bar) ]() {

makes the warning go away.
