<\/span>This hotfix actually fixes 5 bugs:<\/p>\n

<\/span><\/p>\n

<\/p>\n

 <\/p>\n

<\/span><\/p>\n

1. <\/span>function<FT>::swap()<\/span> was broken by the Small Functor Optimization in VC9 TR1 (the Feature Pack).  This broke <\/span>vector<function<FT>><\/span> in VC9 SP1.  “Broken” meant “compiling but crashing”.<\/p>\n

<\/span><\/p>\n

<\/p>\n

 <\/p>\n

<\/span><\/p>\n

2. <\/span>vector<pair<X, string>><\/span> nonconformantly required <\/span>X<\/span> to have a default constructor.  (This is a specific example of a general bug: <\/span>vector<pair<string, X>><\/span>, <\/span>vector<pair<X, vector<int>>><\/span>, etc. were also affected.)<\/p>\n

<\/span><\/p>\n

 <\/p>\n

<\/span><\/p>\n

3. <\/span>vector<tuple<X, Y, string>><\/span> nonconformantly required <\/span>X<\/span> and <\/span>Y<\/span> to have default constructors.  (This is a specific example of a general bug, see above.)<\/p>\n

<\/span><\/p>\n

<\/p>\n

 <\/p>\n

<\/span><\/p>\n

4. <\/span>vector<array<X, N>><\/span> nonconformantly required <\/span>X<\/span> to have a default constructor.<\/p>\n

<\/span><\/p>\n

<\/p>\n

 <\/p>\n

<\/span><\/p>\n

5. Random distributions were broken, triggering infinite loops and emitting bogus results.<\/p>\n

<\/span><\/p>\n

<\/p>\n

 <\/p>\n

<\/span><\/p>\n

If you have any questions, I’ll be happy to answer them in the Comments.<\/p>\n
