bump importance, since it's blocking Phobos PR#2266.

Hmm, actually, this bug appears to have been fixed on git HEAD. Could you try again please?

I take that back. This bug is still triggering when compiling with -O. I'm going to try to reduce it.

Minimal failing test case: ----- // Compile with: dmd -O bool prop(real x) { return false; } double f(real) { return double.init; } void main() { real fc = f(real.init); if (fc == 0 || fc.prop) {} } ----- The ICE goes away if compiling without -O. Looks like an optimizer bug.
