> The only difference is that the new change pass "-fsanitize=undefined",
not -fsanitize=undefined. Does this make the difference?
Yes, you are correct.
When I use:
```
ifeq ($(CONFIG_SIM_UBSAN),y)
ARCHOPTIMIZATION += -fsanitize=undefined
else ifeq ($(CONFIG_MM_UBSAN_ALL),y)
ARCHOPTIMIZATION += -fsanitize=undefined
endif
```
I get no UBSan warnings at all.
When I use:
```
ifeq ($(CONFIG_SIM_UBSAN),y)
ARCHOPTIMIZATION += "-fsanitize=undefined"
else ifeq ($(CONFIG_MM_UBSAN_ALL),y)
ARCHOPTIMIZATION += "-fsanitize=undefined"
endif
```
I get some warnings, both for UBSan and my code.
So it seems like in the first case UBSan is not actually working.
Anyway, the original issue remains: UBSan fails itself.
