[CMake] Dart / ExperimentalMemCheck -- leaks not reported

Hi,

I have made a ctest script to run the ExperimentalMemCheck task on a
C++ test project which has memory leaks.
The CTest process works fine: compilation alright, valgrind is run,
finds leaks and reports are submited to the server. But unfortunatly
the `DynamicAnalysis.xml' does not contain the leaks :/

Here is the ctest file:

$ cat ExperimentalMemCheck.cmake
SET (CTEST_SOURCE_DIRECTORY "$ENV{PWD}")
SET (CTEST_BINARY_DIRECTORY "/tmp/experimental/$ENV{PROJECT_NAME}/memcheck")

SET (CTEST_CVS_COMMAND "/usr/bin/svn")
SET (CTEST_CVS_CHECKOUT "${CTEST_CVS_COMMAND} co $ENV{PROJECT_SVNURL}
${CTEST_SOURCE_DIRECTORY}")

# which ctest command to use for running the dashboard
SET (CTEST_COMMAND "ctest -VV -D ExperimentalBuild -D
ExperimentalMemCheck -D ExperimentalSubmit")

# what cmake command to use for configuring this dashboard
SET (CTEST_CMAKE_COMMAND "cmake")

# should ctest wipe the binary tree before running
SET (CTEST_START_WITH_EMPTY_BINARY_DIRECTORY TRUE)

# this is the initial cache to use for the binary tree, be careful to escape
# any quotes inside of this string if you use it
SET (CTEST_INITIAL_CACHE "
MEMORYCHECK_COMMAND:FILEPATH=/usr/bin/valgrind
")

# set any extra envionment variables here
SET (CTEST_ENVIRONMENT
  "CC=gcc"
  "CXX=g++"
  "CXXFLAGS=-g -O0 -Wall -W -Wshadow -Wunused-variable
-Wunused-parameter -Wunused-function -Wunused -Wno-system-headers
-Wno-deprecated -Woverloaded-virtual -Wwrite-strings -fprofile-arcs
-ftest-coverage"
  "CFLAGS=-g -O0 -Wall -W -fprofile-arcs -ftest-coverage"
  "LDFLAGS=-fprofile-arcs -ftest-coverage"
)


Here is an overview of the output

The log shows that:
- Valgrind properly finds the leaks,
- The end of the log contains:

      -- Processing memory checking output:
      Memory checking results:
      Submit files (using http)

... which doesn't sound good :)


So as expected here is the XML log:

$ cat titan___Linux-g++___20070422-1422-Experimental___XML___DynamicAnalysis.xml

I don't really know what is wrong in my configuration, I suppose the
valgrind output is not properly parsed or not written on the
appropriate file descriptor.

Here are the tools I use
$ valgrind --version
valgrind-3.2.3-Debian
$ cmake --version
cmake version 2.4-patch 6
$ ctest --version
ctest version 2.4-patch 6
$

If you have already encountered this problem or see something wrong, I
would be glad to have some feedback (or any clues for my
investigations).
You can find the full ctest log in attachment.

BTW: my thanks to Dart crew, it needs some time to understand the
philosophy, but it is really worth to.

Thank you by advance
Cheers
