------- Comment #7 from danglin at gcc dot gnu dot org 2009-07-29 17:09 -------
In the 'ch' pass, we have:
<bb 2>:
a.85 = a;
SR.155_25 = b._M_value;
...
This gets transformed in the 'cplxlower' pass to
<bb 2>:
a.85 = a;
SR.155$real_7 = REALPART_EXPR <b.86._M_value>;
SR.155$imag_1 = IMAGPART_EXPR <b.86._M_value>;
However, b.86 is not declared or assigned in the gimple.
