11627,"small_vector<T,n>::swap( ) appears to be broken",benjamin.redelings@…,Ion Gaztañaga,"The small_vector class seems like it could be really useful!  However, it seems to have a broken implementation of the swap( ) member function.

The first test case creates a small_vector<int,10> of size 2.  Swapping fails to clear the vector that is swapped from.

bredelings@transposon:~/Devel/bali-phy/master$ g++ test.C -I boost/include/ -std=c++14
bredelings@transposon:~/Devel/bali-phy/master$ ./a.out 
v.size() = 2   w.size() = 0
 swapping v and w ...
v.size() = 2   w.size() = 2


The second test case creates a small_vector<int,10> of size 11. Swapping seems to work, but apparently corrupts the heap:

bredelings@transposon:~/Devel/bali-phy/master$ g++ test2.C -I boost/include/ -std=c++14
bredelings@transposon:~/Devel/bali-phy/master$ ./a.out 
v.size() = 11   w.size() = 0
 swapping v and w ...
v.size() = 0   w.size() = 11
