--- Comment #4 from Campbell <rlcamp.pdx at gmail dot com> ---
I hit this today in gcc 14.2.1, on
__attribute((packed)) struct ConfigDescriptor {
uint8_t bLength;
uint8_t bDescriptorType;
uint16_t wTotalLength;
uint8_t bNumInterfaces;
uint8_t bConfigurationValue;
uint8_t iConfiguration;
uint8_t bmAttributes;
uint8_t bMaxPower;
};
This was a particularly nefarious one to debug, as the kernel only validates
the lack of packing on this descriptor when plugged in through a USB hub, and
not directly, so the incorrect code was able to persist in production for
years...
