# Failed test 'Got exception when shm write fails'
# at t/Test2/modules/API/Instance.t line 555.
# Value: IPC shmwrite() failed (Ungültiges Argument) this is a fatal error at t/Test2/modules/API/Instance.t line 540.
# Does not match: (?^:IPC shmwrite\(\) failed \(Invalid argument\) this is a fatal error)
