Summary0012490: Coverage counts 0 lines when path too long
DescriptionIf the path to the .gcov files to be generated becomes to long, there is no error message, the LOC counters are just 0.
Steps To ReproduceDropping the attached files in a directory like '/home/pascal/ctest-cov' and running
mkdir d && cd d && cmake .. && make && make ExperimentalTest && make ExperimentalCoverage

yields
    Covered LOC: 2
    Not covered LOC: 0
    Total LOC: 2

But when using 'abcdefghijklmnopqrstuvwxyz01234567890123456789' instead of 'd',
it yields
    Covered LOC: 0
    Not covered LOC: 0
    Total LOC: 0
Additional Informationcmake version 2.8.5
ctest version 2.8.5
c++ (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1
gcov (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

long.log and short.log is the output of 'ctest --debug -VV -D ExperimentalCoverage' in long and short paths respectively.

I suspect the fix for 0011717 is the cause of this, and the other related bug...
