--- Comment #3 from Alexander Cherepanov <ch3root at openwall dot com> ---
Bug 85957 is definitely similar. I've added it and a couple of others to "See
Also".
Some differences:
- testcases here use comparisons to jump from FPs to integers while bug 85957
uses casts;
- the exploited discrepancy here is between in-register and in-memory
(run-time) results of type `double` while in bug 85957 it's between
compile-time and run-time results;
- it's probably possible to fix bug 85957 by enhancing the dom2 pass while it
will probably not help here.
Whether it warrants a separate bug report it's hard for me to say.
