[CMake] random BAD_COMMAND error on ctest

[BILODEAU Andre]

Hello
 
I have finally the simplest setup which reproduces random BAD_COMMAND errors:
- no compilations or produced binaries, justs tests
- tests are called without arguments or set properties
 
There are 20 tests, all of the form 
    add_test (test_02 ${CMAKE_CURRENT_SOURCE_DIR}/test_driver)
 
All tests call the same trivial test driver, with grep called as a sub-process:
-------------
#!/bin/sh
SRCDIR="../../test"
########################################
# Run simple grep command
grep dummy ${SRCDIR}/CMakeLists.txt
exit 0

-------------
 
The project files are provided as attachment. I ran the following commands from the buid directory:
cmake ../test
make
make test
 
Running make test over and over produces randomly (average of about 1 test over 20) some lines of the form
16/20 Test #16: test_16 ..........................***Not Run   0.44 sec
      Start 17: test_17
 
The test finally being reported as failed, when there is no reason for that.
 
If the driver is further simplified by removing the grep command, no test fails.

cmake version:  2.8.10.2
 
My conclusion is that there is a process management problem with ctest. As a consequence, this version of cmake can't be used for tests involving any sub-process.
 
Can this be submitted as a bug report ? If so, what is the procedure ?
