how to fix?
(Couldnt see your 6.2 result, did I snip it?)
Upgrade to 6.2, or for better results, 7-CURRENT
$ uname -a && ./stl_test

Is your test for 4 using GCC 2.95 ? C++ in GCC 2.95 is «interesting» in
the shortcuts it takes.
We didn't include 6.2 report in mail, but we experience same probles.
results are exactly as yours above (alloc time 2.7 clear time 5.6)
BSD 4 test was using compiler 2.95
Is there any way to fix it without upgrading to 7.0?
