        $stmt2 = "SELECT B, C FROM test WHERE A = ? AND B = ?";

        $stmth2 = $dbh->prepare($stmt2);
        $stmth2->execute(array('A', 'B'));

Tested this report on current branch master/7.2. Issue is not reproducible.
Probably it was fixed during previous commits.

D:\Projects\Php\phpdev\vc14\x64>x64\Debug_TS\php.exe x64\Debug_TS\test.php
array(1) {
  [0]=>
  array(2) {
    ["B"]=>
    string(1) "B"
    ["C"]=>
    string(1) "C"
  }
}
OK!
D:\Projects\Php\phpdev\vc14\x64>

DDL:

SET SQL DIALECT 3;

CREATE TABLE TEST (
    A  DT_CHAR /* DT_CHAR = VARCHAR(1) */,
    B  DT_CHAR /* DT_CHAR = VARCHAR(1) */,
    C  DT_CHAR /* DT_CHAR = VARCHAR(1) */
);

COMMIT;

INSERT INTO TEST (A, B, C)
          VALUES ('A', 'B', 'C');
