Scan-build somehow replaces the compiler. My guess is that you tell scan-build to substitute clang but "make" is really using gcc or something? I reported something strange about the compilers on TravisCI some time ago but I can't find it anymore. I think I remember on OSX they always use clang even if you define gcc. Maybe it makes sense to reach out to TravisCI support in case this is a bug on their end? Based on your work I tried the following and it seems to work: https://travis-ci.org/larsxschneider/git/jobs/205507241 https://github.com/larsxschneider/git/commit/faf4ecfdca1a732459c1f93c334928ee2826d490 - Lars
