REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
When I have compiled the only file with the syntax error, everything worked. Only when I want to build the whole program, the error occurred. You can download the problematic projects (one project and the second one serving as a library or framework) at
