No, the cairo deimos binding is passed as a static library: so 
the *.a file as a source then only the search path (-I). Then LDC 
is called via LDMD2 (with exactly the same command line that's 
passed when I use DMD).

The project also does the same (*.a + I<source root>) with libX11 
(which is several order of magnitude bigger then cairo) and no 
similar error has occured.

On the other hand I've already found several issues in the old 
cairo binding so I really don't accuse LDC to have a bug, 
furthemore the real problem I had is now fixed 
(dmd_personnality). I'll report a bug if it happens with another 
library.
