| I suspect it's related to linking… | |
| So, a while back Orlando had fixed some things in Foundation (which still haven't been merged yet). | |
| The symptom is that you'll get an error from unwrapping a nil. | |
| When I test OSULogger (b, in the example above) without the patched Foundation I get the error. | |
| Once I patched it, the tests pass. Then, with the same libraries and everything, | |
| if I pull in OSUOpenCL (a) which depends on OSULogger, the tests in logger fail in the | |
| same way as the unpatched Foundation | |

In C, the signness of char is undefined. A convention is set by either the platform, such as Windows, or by the architecture ABI specification, as is typical on System-V derived systems. A subset of known platforms germane to this discussion and their char signness is provided below.
