 Probably.  I was using the gcc trunk.  Perhaps I should have filed the PR
 for gcj.
 
 As a workaround I commented out all the marking code in libjava/boehm.cc,
 so the GC scans all Java objects conservatively.  My tests ran fine
 afterwards.  This suggests that something was wrong in reflection, on
 which the marking code depends.  So perhaps something changed in the class
 layout, or gcj is really generating incorrect code... I'm not sure.
