This one is expected and intentional. Type is an enum class with quint16
underlying type, so it cannot store all 65536 values on 15 bits.

No, it isn't. The values in question are all less than 9 bits in size.
The issue appears to be that QT_POSIX_IPC isn't #define'd in qtcore-config.h.
This is the configure.cmake content:
LABEL "Defaulting legacy IPC to POSIX"
CONDITION TEST_posix_shm AND TEST_posix_sem AND (
FEATURE_ipc_posix OR (APPLE AND QT_FEATURE_appstore_compliant)
OR NOT (TEST_sysv_shm AND TEST_sysv_sem)
>From the cmake output, we should have:
TEST_posix_shm = ON
TEST_posix_sem = ON
TEST_sysv_shm = OFF
TEST_sysv_sem = OFF
So this condition should have been TRUE. But isn't.
BTW, the iOS build said:
Defaulting legacy IPC to POSIX ......... yes
So the middle condition of appstore-compliance did work.
