Between 20060207 and 20060209 the testcase started failing like this:
1.exe:
/usr/src/pcarlini/gcc-head/gcc/libstdc++-v3/testsuite/25_algorithms/prev_permutation/1.cc:75:
void test4(): Assertion `array[i] == 5 - i' failed.
FAIL: 25_algorithms/prev_permutation/1.cc execution test
Seems a miscompilation: the problem goes away at -O1. By the way, the failing
test4 is pretty easy to make self contained, I'm attaching it for convenience.
