The plugin is already disabled for ASAN builds with GCC. Should I just disable it for ASAN builds in general? Or is this linked to the markdown test?

Thank you for reporting the problem.

@sanssecours Did xerces work for you with ASAN in some clang version?

Did xerces work for you with ASAN in some clang version?

As far as I can tell from a recent Travis build, the combination

seems to work. The test fails on my computer (macOS 10.13.4, Xerces 3.2.1, LLVM 6.0.0) though:

ingwinlu commented 6 years ago

Alright, fully disabling it is.

markus2330 commented 6 years ago

It seems like with 

Ubuntu 14.04
Clang 6.0.1
Xerces 3.1

ENABLE_ASAN works. Why disabling it then? Do we have Ubuntu already as Docker Image?

sanssecours commented 6 years ago

Why disabling it then?

I think it makes sense to disable the plugin too. Since the AddressSanitizer

I assume we have a real memory leak here.

markus2330 commented 6 years ago

Okay, thank you for the info.

I assume we have a real memory leak here.

Which is most likely part of xerces itself. The leak seem to happen in XMLPlatformUtils::Initialize (); (I did not look at all occurrences, though)

ingwinlu commented 6 years ago

could it be that we have the memory leak in the mount command? It was the same for the validation.md test with ASAN builds.

markus2330 commented 6 years ago

The memory management in libtools (which implements mount) is not done manually (but via C++ RAII) so it is unlikely that there are memory leaks but it is possible. libstdc++ itself, however, usually has memory leaks (They internally allocate some memory pools which are never freed. Valgrind suppresses these pools.). Yesterday @waht reported that the dump plugin might be affected by this problem (and thus nearly every mount command because dump is the default storage).

It would be interesting if ini as default plugin (KDB_DEFAULT_STORAGE=ini) improves the ASAN situation.

Which mount command in validation.md causes the problem?
