I have been attempting to understand the differences between compilers
and environments when running tests on Boost Phoenix.
-
Some environments are limited in the memory available for testing and
I have broken some large tests into smaller pieces.
-
Some of the problems experienced in testing are specific to particular
compilers being used.
-
Some problems have occurred with several more recent compilers.
-
One problem is that I do not have access to all of the compilers used
in the tests or by users.
-
My system is Ubuntu
12.04
-
I have expanded the compilers I have available to include the
following
-
gcc 4.6, 4.8.2, 4.9.0
& 4.9.2 (I will add 5.0 when released)
-
Clang 3.4, 3.5 &
3.6 (pre-release in the last case)
-
The most difficult problems to diagnose have been some which occur
when the compilation uses optimization.
-
Some of the boost tests use optimization but most do not.
-
It is not usually documented which tests are optimized.
-
This means that a lot of tests run there which fail when optimized.
-
This has made the identification of the cause of the problems
more difficult.
