Hi Andrew: You may be doing this already, but for the others here I suggest using the convenient -DVALGRIND_ALL_TESTS=ON which systematically applies the --debug option to all test targets (which is most of them) that use plplot-test.sh. That's how I found that plcolorbar -O3 issue (as discussed previously here) with the "make test_noninteractive" command. As you have found it is a really tough memory management issue to figure out since optimization (which is required to generate the memory management issue) makes using gdb rather difficult. So it would be great if you could figure it out because diagnosing the problem is certainly beyond my level of gdb expertise. > I've fixed a number of other issues, but some still remain for fortran / C++. > I'll try and address these if I can, but I'd recommend others to try this test > as well. Thanks for those additional fixes. For the others here, -DVALGRIND_ALL_TESTS=ON will be ignored if valgrind is not installed (or cannot be installed). But for those with access to valgrind I strongly second Andrew's appeal. All you have to do is use the -DVALGRIND_ALL_TESTS=ON cmake option and run the normal "make test_noninteractive" and "make test_interactive" test commands. Alan __________________________ Alan W.
