Bug 1981 – ICE(cgcod.c 1523) -O -inline -release, no test case

I can only get it to happen with my full code base ~2,000 lines, if I can find a smaller failure case I'll post it. The problem seems to be very fragile. If I don't inline it goes away, if I don't use release mode it goes away, or if I don't optimize it goes away...it only happens with all 3 options enabled. Also if I switch from: bool func(float2f s, float2f e){ bool retval = false; retval |= foo(s, e, a, b); retval |= foo(s, e, b, c); retval |= foo(s, e, c, a); return retval; } To: bool func(float2f s, float2f e){ bool retval = false; retval = foo(s, e, c, a) || foo(s, e, b, c) || foo(s, e, a, b); return retval; } The problem goes away.

Unfortunately neither 1981 nor 1709 has a test case. Almost certainly a duplicate. *** This issue has been marked as a duplicate of issue 1709 ***
