I retract my previous replay.
With/without the "default n" in the choice menu, I confirmed the problem happened (in the latest Linux as well as U-Boot).
I hope somebody follows up...

Hi Mateusz, (CCing linux-kbuild, which I think the best place to discuss this topic)
I think "default n" in the choice entry is weird because the choice is not boolean.
Without it, the weird thing you saw did not happen on my box.
Anyway, I'd like Kconfig to say something if it is really a syntax error.
I hope comments from Kconfig experts.

Hi all,
I have found weird feature of Kconfig. If I misused something, please let me know - I found at least one place where the same error occurs.
Let's consider the following Kconfig (you can put it anywhere in the source tree): <-------------- copy -----------------> menu "Testmenu" choice prompt "Problem to solve" optional default n help Solve one of great world problems
config SOLVE_HUNGER bool "Hunger"
config SOLVE_WARS bool "Wars"
config CURE_CANCER bool "Cancer"
endchoice
config TREES default n bool "Plant trees in garden" endmenu
config BLAH default n bool "Totally unrelated option"
<------------- paste ------------------->
Now, select HUNGER important problem to solve; Warning - select it with space, _not_ enter + selection from list; Then select either TREES or BLAH.
Weird thing is - SOLVE_HUNGER is unselected.
It doesn't happen when you select (anything) by entering selection menu (i.e. enter). Even if you deselect option and then select it with space.
It happens both in menuconfig and nconfig.
It happens both in recent U-Boot b57843e6 and Linux kernel ece62678.
Unfortunately my knowledge of Kconfig is very limited so your help would be appreciated.
