[Bug libstdc++/42381] New: deque shouldn't reserve that much memory

2009-12-15 Thread kraemer at informatik dot uni-kl dot de 
In bits/stl_deque.h, line 80ff the minimal allocated size is set fixed to 512.
This should be configurable, at least via a macro.
In case of small memory systems (embedded devices) resveration of this amount
of memory is much too high.

thanks a lot.
in our scenario it showed 8 buckets to be the best. but this may vary by usage.
