" YYYY"); Expected result: ---------------- Exception: XXXX class@anonymous... YYYY in file:3 Stack trace: #0 {main} Actual result: -------------- Exception: XXXX class@anonymous in /in/mft0e:3 Stack trace: #0 {main} ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74999&edit=1
