Yeah jens, I know. I have created the packages and the issue remains the same. I am repeating the steps as I am typing this message to make sure it's not my fault.
UPDATE: Yep, the issue remains the same. Can someone update to latest HEAD revision, compile it, and try a #define something() macro to see whether it crashes on first parenthesis or not?
UPDATE #2: Now that I have compiled .deb packages myself and managed to reproduce the crash, gdb reports the following:
Program received signal SIGSEGV, Segmentation fault.
