Yes, I just tried that and I cannot reproduce it this way either. No can I reproduce it with a minimal example with just one int option. The attached Kconfig (from a "Hello, World" example I am writing), however, reproduces it for me reliably: $ rm .config $ ENABLE_FANCY=y .../qconf Kconfig Then, in the "Fancy options" select "Name fallback" and inside double click on "Max times to ask for name" to activate the edit box. After that, clicking anywhere outside of this edit box causes a SIGSEGV for me. Can you try that?
