[Bug libstdc++/41448] New: std::sort on std::vector with certain values leads to segfault in the vector destructor

[4ernov at gmail dot com]

I suffer strange segfault in program using std::sort on std::vector<float>. The
segfault occures in destructor of sorted std::vector after several sort/clear
cycles. The values to reproduce the crash is actually decoded audio. I'm so
sorry, I can't evaluate the proper sequence of bad values so I've uploaded the
whole chunk here: http://downmusic.ru/test1 (110 mb sorry but i found no better
way...) I know it's not the ideal way but maybe it helps.

As far as I found out it is because of NaNs in float vector. Also,
std::stable_sort never leads to crash as I've tested.
