#13380: data-driven tests' join operator `+` corrupts first column
------------------------------------+-------------------------------
 Reporter:  Addy <aclaure@…>        |      Owner:  Gennadiy Rozental
     Type:  Bugs                    |     Status:  new
Milestone:  To Be Determined        |  Component:  test
  Version:  Boost 1.65.0            |   Severity:  Problem
 Keywords:  data-driven-tests join  |
------------------------------------+-------------------------------
 Consider the following code:

 {{{
 BOOST_DATA_TEST_CASE(
       sampleTest,
       (data::make(1) ^ data::make(2)) + (data::make(3) ^ data::make(4)),
       var1,
       var2)
 {
   std::cout << var1 << "," << var2 << std::endl;
 }
 }}}

 The output I'd expect to see is:

 {{{
 1,2
 3,4
 }}}

 However it appears that `var1` gets corrupt:

 {{{
 $> ./MyTests --run_test=Tests/sampleTest
 Running 2 test cases...
 202875304,2
 202875304,4

 *** No errors detected
 $> ./MyTests --run_test=Tests/sampleTest
 Running 2 test cases...
 83976616,2
 83976616,4

 *** No errors detected
 }}}
