Description Frank Hoeflich 2009-02-13 02:40:06 UTC 
To reproduce:

1. Get a fresh 02.2009 buildroot.
2. make menuconfig
3. Navigate to Graphic Libraries and applications
4. Navigate to X Window System server
5. Select tinyx.  Boom.

My screenshot with error message from Kconfig is attached.  The message is:

/bin/sh: line 4: 16472 Segmentation fault      KCONFIG_AUTOCONFIG=package/config/buildroot-config/auto.conf KCONFIG_AUTOHEADER=package/config/buildroot-config/autoconf.h package/config/mconf Config.in

If you select wchar in Toolchain between steps 2 and 3, tinyx is selected normally.

Forget the screenshot - 75kb limit. :-@(

It seems like Kconfig doesn't like comment entries in choice selections. The comments were added to make it clear why you can't select xorg/tinyx, but you are ofcourse not supposed to be able to select those comments.

It seems to me that the easiest fix (besides reporting upstream, the bug exists in the latest kernel as well) is to move the comments outside the choice / endchoice
