mat...@mpia-hd.mpg.de <mat...@mpia-hd.mpg.de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mat...@mpia-hd.mpg.de --- Comment #13 from mat...@mpia-hd.mpg.de <mat...@mpia-hd.mpg.de> --- This bug should be reopened because the source code GCCMain.java is only in the gcj version of org/eclipse/jdt/internal/compiler/batch/GCCMain.java . It does *not* exist in the associated current ecj-4.3.2 repository of the eclipse project, which does not have any GCCMain.java at all. Certainly the problem is in the gcj, not in the eclipse project. They cannot fix a bug that is not theirs. See also http://download.eclipse.org/eclipse/downloads/ and http://stackoverflow.com/questions/2567230/gcj-creates-duplicate-dummy-symbol . The problem still exists in ecj-4.9.jar .
