Besides the bug fix I posted before, our Cray system administrator warned me that there are (were) machines which trap integer overflow, and where above code would not work. He proposed to use a hash function employing exclusive or operations instead. In contrast to fixing the bug for which I sent the patch, this is s however definitively not an urgent problem. It should be kept in mind however in case that we ever encounter a modern machine trapping integer overflows.Dear Boost Jamers,Our local Cray adminstrators (Bruno Loepfe from ETH and Olivier Byrde from Cray) found a bug in the boost jam sources. it is in the file hash.c: keyval = keyval * 2147059363 + *b++;
