I remember I mentioned (many weeks ago) that we'd need to #ifdef some of this stuff into compartments so that it didn't affect non zlib builds. I didn't remember to check for that before giving the LGTM. That is certainly killing at least some bots. I think the downstream bots that Petr mentioned are however actually linking in zlib. It isn't clear why this is breaking those but I'll try and look into that today.


Thanks. I tried building with -DLLVM_ENABLE_ZLIB=OFF (ubuntu x64) and the tests seem to not run and come out as "unsupported" The weird thing is, the test failures seem to indicate that the flag was not set properly (which I'd think wouldn't depend on zlib).
