The important test here is tst_dumpers.

The same build can be used to check the dumpers under different
conditions by using environment variables as follows:

   QTC_DEBUGGER_PATH_FOR_TEST - path to a GDB or LLDB binary

   QTC_QMAKE_PATH_FOR_TEST - path to a Qt version

   QTC_MAKE_PATH_FOR_TEST - path to a "make".
      Used for GDB only, defaults to "make" except on Windows,
      where it defaults to "mingw32-make"

   QTC_USE_GLIBCXXDEBUG_FOR_TEST - (0/1) to switch between GCC's
      "normal" standard library, and the "debug" version
      (this will add DEFINES += _GLIBCXX_DEBUG) to the .pro

   QTC_BOOST_INCLUDE_PATH_FOR_TEST - include path for boost libraries
      only necessary if you have more than one version in different
      paths installed or if a non-standard path has been used

  (QTC_MSVC_ENV_BAT - to set up MSVC)
  (QTC_CDBEXT_PATH (optional) - path to the cdbextension
      defaults to IDE_BUILD_TREE/IDE_LIBRARY_BASENAME/qtcreatorcdbext64)

   QTC_USE_CMAKE_FOR_TEST - Use cmake to build test cases (incomplete)

The tests should be used for automated testing, but can also
be used for dumper development and fixing.

Combinations that should always succeed are:

   GDB (>=7.4), Linux (32/64), Python (2/3), Qt (4/5) - debug.

Partially work should:

   Qt (4/5) - release
   LLDB (Mac)


By default, only successful tests are cleaned up (use
QTC_KEEP_TEMP_FOR_TEST to override).

Failing tests leave a qt_tst_dumpers_XXXXXX directory behind,
with a 'doit.pro' which can be directly opened in Creator.
There's always a 'main.cpp' file, containing at least one
call to a function 'breakHere()'. Put a break point there,
and hit F5.

The file 'input.txt' contains the commands sent to GDB
in case something needs to be examined with the CLI debugger.
