Regehr: GCC 4.8 Breaks Broken SPEC 2006 BenchmarksRegehr: GCC 4.8 Breaks Broken SPEC 2006 BenchmarksPosted Mar 25, 2013 21:09 UTC (Mon) by mansr (guest, #85328)In reply to: Regehr: GCC 4.8 Breaks Broken SPEC 2006 Benchmarks by xorbe Parent article: Regehr: GCC 4.8 Breaks Broken SPEC 2006 Benchmarks
The problem is that the source code is self-contradicting when interpreted strictly. While your observation is correct, the source also implicitly (through the d[k] array access) promises that k < 16. When given conflicting information like this, the interpretation is unpredictable. That is (part of) what undefined behaviour means. Get over it.
