I think this is the same failure as the current bootstrap problem on 
ppc-darwin.
For the bootstrap problem we have the following CONST_DECL:
  static struct gnat__strings__string_access C.828 = 
{.P_ARRAY=(character[(long int)
<PLACEHOLDER_EXPR struct 
gnat__strings__string_access>.P_BOUNDS->LB0:(long int)
<PLACEHOLDER_EXPR struct gnat__strings__string_access>.P_BOUNDS->UB0] 
*) "",
.P_BOUNDS=&{.LB0=1, .UB0=0}};

Notice how we take the address of a CONSTRUCTOR this is wrong and we 
should never do that.
Which makes this a front-end bug.
