Description Juan Magallon 2013-10-23 13:14:45 CEST 
I was bitten by this g++ bug:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58800

The proposed solution involves changing a couple '__last - 2' to
'__Last - 1' in libstdc++-v3/include/bits/stl_algo.h

I have tested changign it in system includes and my user code works again,
but I thikn it should be changed in gcc sources and compilers rebuilt.

And I don't know how much user space code is affected (packages using
nth_element) ... Is there an easy way to know this in build system ?

TIA
