Unsurprising... It will never fail during testsuite run, and won't always fail during a bootstrap. > I can't think what the comment would be talking about with pointers not > providing a stable order; I don't see anything that would rely on that. http://gcc.gnu.org/ml/gcc/2005-04/msg00161.html has the details of why the code was put in. Essentially, the Ada boostrap on x86 linux. What's worse is, at the time, it would only occasionally fail, so, a bootstrap that works won't prove anything.
