Bug report

In the library that came with gcc3.3.1, file bits/stl_algo.h, function "search" (version taking a predicate function in addition to iterators):
The second nested while loop in the general case (line 562 in my version) is identical in effect to the first loop immediately before and is redundant. However, a compiler is unlikely to detect that the second loop will never execute.
Both while loops and the following exit test can be combined (for better code) to:
while(true) {
    if (__first1 == __last1)
        return __last1;
    if (__predicate(*__first1, *__first2))
