Note we end up with:
D.770 = COMPLEX_EXPR <D.768 - 4.0e+0, 0.0>;
ca1$imag = IMAGPART_EXPR <D.770>;
ca1$real = REALPART_EXPR <D.770>;

Here is the reduced testcase (fortran):
COMMON TA(6,6)
COMPLEX*16 CA1,CA2,CLAM2
CA2=DCMPLX(F2,ZERO)
CA2=SQRT(CA2)
CLAM2=(EGWG2+CA2)/TWO
DO 40 I=1,4
TA(I,3)=DREAL(CLAM2)
40 CONTINUE
RETURN

This is most likely a dup of bug 18268.

And here is a testcase where we don't use an unitialized variable and no loops either:
COMMON TA,A
COMPLEX*16 CLAM2
CLAM2=DCMPLX(A,2.0)
TA=DIMAG(CLAM2)
RETURN
