 Thanks for your bug report. This is, unfortunatly, a known problem with
 the java.lang.Class vtable - calling several methods on instances of
 java.lang.Class from java code will result in crashing. It has been
 reported that static linking will work around this problem.
 
 See PR gcj/100

 We believe this is an ld.so bug.
 I think we'll know soon.
