Using code:

<< {
        R1
        \once \set Staff.whichBar = ".|:"
        R1*3
        \break
        R1*4
   }
   {
        R1
        R1*3
        \break
        R1*4
   }
>>

compiles fine with 2.12.3, 2.14.2, 2.16.0 and, after converting (\bar
"|:" ->  \bar ".|:") with 2.17.8

But code

<< {
        \once \set Staff.whichBar = "|:"
        R1*3
        \break
        R1*4
   }
   {
        R1*3
        \break
        R1*4
   }
>>

works as expected with 2.12.3 and 2.14.2 but gives a segfault with
2.16.0 and 2.17.8 (again after converting)
