Research project on PHP coverage results

Hi, I am working in IBM in a research project for analyzing code coverage results. We tried getting lcov coverage results from PHP (versions 5.2.9 - 5.2.12) since it is very organized and well documented. We configured using: "./configure --enable-gcov" And built it using: "make lcov" What we always get in the same place is an error message indicating the following: Processing lcov_data/chroot_001_x/tmp/PHPCoverage/php-5.2.12/ext/hash/hash_tiger.gcda geninfo: ERROR: cannot read /tmp/PHPCoverage/php-5.2.12/lcov_data/chroot_001_x/tmp/PHPCoverage/php-5.2.12/ext/hash/hash_tiger.gcno! make: *** [php_lcov.info] Error 2 Finally, our goal is to have the final file "php_lcov.info" with all the collected data from the tests traces. Did we run the right commands? Is there any specific contact that might help us on that?
