I see this message "Error: stack underflow" when a loader menu is presented. It seems that it comes from ficl. This is on a quite recent (< 2 weeks) head. How can I debug this problem? I have one local modification to forth files, but I'm not sure if the problem is caused by it or by something in my boot configuration files. diff --git a/sys/boot/forth/menu-commands.4th b/sys/boot/forth/menu-commands.4th index 9adf30a46b661..813cbf12e9655 100644 --- a/sys/boot/forth/menu-commands.4th +++ b/sys/boot/forth/menu-commands.4th @@ -243,6 +243,21 @@ also menu-namespace also menu-command-helpers TRUE \ loop menu again ; +: toggle_gui ( N -- N TRUE ) + toggle_menuitem + menu-redraw + + \ Now we're going to make the change effective + + dup toggle_stateN @ 0= if + s" inhibit_gui" unsetenv + else + s" set inhibit_gui=1" evaluate + then + + TRUE \ loop menu again +; + \ \ Escape to Prompt \ diff --git a/sys/boot/forth/menu.rc b/sys/boot/forth/menu.rc index 3c7de7138b8ad..ddeccc9679fea 100644 --- a/sys/boot/forth/menu.rc +++ b/sys/boot/forth/menu.rc @@ -126,6 +126,13 @@ set optionsmenu_keycode[6]=118 set optionsansi_caption[6]="^[1mV^[merbose..... ^[34;1mOff^[m" set optionstoggled_ansi[6]="^[1mV^[merbose..... ^[32;7mOn^[m" +set optionsmenu_caption[7]="Inhibit [G]UI. off" +set optionstoggled_text[7]="Inhibit [G]UI.
