I am running Ubuntu pre-6.10 (Gutsy -- the > development version of the distro). Maybe I should try "make > mrproper" first? make mrproper should not do any difference here. I rather think you hit some ncurses bug. If you could add '-g' to HOSTCFLAGS in top-level Makefile and then do: rm scripts/kconfig/mconf.o scripts/kconfig/mconf make menuconfig (to build mconf and to check that the error is still reproduceable). And then run it in a debugger like this: gdb scripts/kconfig/mconf run arch/x86_64/Kconfig ^^^^^^ replace with your actual arch Provoke the error and get a back-trace with 'bt'.
