Some debugging lead to following observation:
Each inserted branch add a color to the list. The original enum defined colors
(about
102), last Color_ignore.
So each branch will now get colors 103, 104, ..., and so on, so that the
original enum
(probably used as 'char') cannot contain the value beyond 127).
Expanding the colors in src/ColorCode.h as in attached, removes the sanitize
messages.
