10632,Problem with range transform with gcc-4.8 optimized,Fabien Nendaz <fabien@…>,Neil Groves,"With gcc4.8, if the option -O is used, the operation "" | transformed(arg1)"" on a transformed range leads to unexpected results.

E.g. if ""initialVec"" is a vector containing any values, the following line gives a null resultVec:[[BR]]
auto resultVec =  initialVec | transformed( arg1 * 2 ) | transformed( arg1 );

This problem is also present with clang (optimized) and visual studio 2013 (in release), but not in debug modes, and not with gcc-4.6.

Note that an operation in the second transformed remove this problem: the following code is working as expected:[[BR]]
auto resultVec =  initialVec | transformed( arg1 * 2 ) | transformed( arg1 * 1 );

This problem has been reproduced with boost 1.49, 1.55 and 1.56.",Bugs,new,To Be Determined,range,Boost 1.55.0,Problem,,,
