I suggest you to try latest available dev-lang/icc (11.1.072).
This thing is really paranoid:

remark #2259: non-pointer conversion from "int" to "unsigned char" may lose significant bits
      unsigned char BlinkerPhase = 0;
      ...
      BlinkerPhase = (BlinkerPhase + 1) & 3;

remark #981: operands are evaluated in unspecified order (tons of them)
      return strcmp( left.c_str(), right.c_str() ) > 0;
