Testing a fix that addresses the problem. With the fix, the dump shows:

Use in stmt: blah (v_1);
is guarded by :
m_6(D) > 100
(.OR.)
n_4(D) <= 9
(.OR.)
r_9(D) <= 19

Operand defs of phi: v_1 = PHI <v_14(D)(13), r_9(D)(3)>
is guarded by :
m_6(D) > 100
(.OR.)
n_4(D) <= 9
(.OR.)
l_11(D) != 0
(.OR.)
r_9(D) <= 19

which is correct.
