| I have been attempting to understand the differences between compilers |
| and environments when running tests on Boost Phoenix. |
| </p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"> |
| Some environments are limited in the memory available for testing and |
| I have broken some large tests into smaller pieces. |
| </li> |
| <li class="listitem"> |
| Some of the problems experienced in testing are specific to particular |
| compilers being used. |
| </li> |
| <li class="listitem"> |
| Some problems have occurred with several more recent compilers. |
| </li> |
| <li class="listitem"> |
| One problem is that I do not have access to all of the compilers used |
| in the tests or by users. |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "> |
| <li class="listitem"> |
| My system is <a href="http://www.ubuntu.com/" target="_top">Ubuntu </a> |
| 12.04 |
| </li> |
| <li class="listitem"> |
| I have expanded the compilers I have available to include the |
| following |
| </li> |
| <li class="listitem"> |
| <a href="https://gcc.gnu.org" target="_top">gcc </a> 4.6, 4.8.2, 4.9.0 |

| <li class="listitem"> |
| The most difficult problems to diagnose have been some which occur |
| when the compilation uses optimization. |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "> |
| <li class="listitem"> |
| Some of the boost tests use optimization but most do not. |
| </li> |
| <li class="listitem"> |
| It is not usually documented which tests are optimized. |
| </li> |
| <li class="listitem"> |
| This means that a lot of tests run there which fail when optimized. |
| </li> |
| <li class="listitem"> |
| This has made the identification of the cause of the problems |
| more difficult. |
