This is *not* the gcj that is installed with FC3, I compiled it separately. The libgcj is *not* the one installed with FC3, its the one I compiled from GCC 4.0.0 Attempting to run JING (a Relax NG based XML validator) after compilation with GCJ yields a SIGSEGV in _Jv_Linker::prepare_constant_time_tables in file libjava/link.cc at line 519. The code in this method traverses a list. One of the pointers (klass0) in that list has value 1 which when de-referenced causes the SIGSEGV. To recreate: 1. wget http://www.thaiopensource.com/download/gcj/jing-20030619.tar.gz 2. tar zxf jing-20030619.tar.gz 3. configure 4. make (13 warnings about deprecated classes) 5. cd test 6. make JING is 330K of Java source so I didn't attach it. But, you can get it from the URL above. I don't really care if its against the "reporting rules" for GCC. This is a runtime error, not a compilation error (that I can tell).
