Since about 3 weeks bootstrap is failing due to comparison failure on java/decl.o (no other object file is affected). It first started with r115810, then went away with r115850, but reoccurred with r115851. Since then it reoccurred often but irregularily. Bootstrap is currently failing for three days now. When running the compilation command for java/decl.o manually the resulting object file is identical to the stage2 object file, which means that there is an environmental dependency in the generated code. Bootstrapping with --enable-checking=all didn't show any error, the comparison failure remained.
