PATH is updated just before running the tests.
i just checked that clang sanitizer should indeed show symbols when llvm-symbolize is in the PATH. And I see that it should be the case according to .travis.yml. Log also shows that vim was compiled with -g. No idea why the stack did not contain symbols then. I can't reproduce the asan error with vim when running tests with asan on my machine.
