This does not fail for me... Neither the original test case nor the reduced
one. The compiler I used was GNU C++ version 4.1.0 20051029 (experimental)
(x86_64-unknown-linux-gnu)

This does ICE for i686 or for AMD64 -m32. For 64 bits it passes for me.

Reduced testcase:
typedef __complex__ double cdouble;
inline cdouble to_complex(double r) {
cdouble z;
__real__ z = r;
return z;
}
cdouble elt_zero() {
return to_complex(0.0);
}

The inliner is
