Reproducing antlr/antlr3#128
cd antlr3-issue128
ln -s /path/to/antlr-3.5-complete-no-st3.jar antlr.jar
./build.sh # shows correct behavior
nano bugTreeRewriter.g # use nano or your favorite text editor to uncomment rewrite=true;
./build.sh # breaks
The bug reproduces with antlr-3.5-complete-no-st3.jar (sha256sum=89fe660f7bac358310940b9edeaf654f443b890c5fbc4fb75976c754e508c180). I have not tested earlier or later versions.
