Hmm, it doesn't reproduce for me with a cc1 cross and your reduced testcase.

I think there's a dup and/or Martin already fixed this with
g:e4c02ce4ab6fce1148f4025360096f18764deadf - can you confirm?

Reduced program:

struct {
  unsigned a : 10   
} b;
c;  
d() {   
  c = b.a;  
  if (c == 8 || c == 0) 
;   
  else if (c > 8 * 8)   
;   
  else if (c < 8 * 8)   
e();
}
