This appears to be fixed in HEAD.  I added 

   print *, example%vals

within the associate statement.  With gfortran 10.someversion, I
get

% gfortran10 -o z a.f90
% ./z

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
#0  0x80081f6bb in ???
#1  0x80081e876 in ???

#4  0x400d8a in ???
#5  0x400e37 in ???
#6  0x40083f in ???

With HEAD, I get

% gfcx -o z a.f90
% ./z
          42
