Hello,
This snippet (Notation Reference 1.6.1) works fine on 2.18.2-1 but is
incorrect on 2.19.82-1 (the SystemStartSquare on staff b vanishes).
\new StaffGroup
\relative c'' <<
\set StaffGroup.systemStartDelimiterHierarchy

(SystemStartSquare b) ) c ) d)
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }

What's happening is that the default "collapse-height" is set such that
grouping braces/brackets/etc. will not normally show when they only
contain a single staff.
Try adding in this something like this:
%%%%
\override StaffGroup.SystemStartSquare.collapse-height = #0
%%%%
