building from cvs

hi all,

first of all kudos to you all. You are doing a great job.

I wanted to test some of the newer APIs in libgcj and so I checked out
the gcc source and did a fresh compile. (For instance the
ByteBuffer.allocateDirect(I) )

After some problems, I managed to compile the whole thing and install it
into a custome prefix $HOME/gcc.

I sourced my gcc prefix (PATH,LD_LIBRARY_PATH) and compiled a simple
Test.java. 
Now, no matter which Java code, I compile, after trying to run the
binary I get a sigsegv. Gdb told me that the natClass.cc tries to access
a apprantly Null pointer in :

_Jv_linkExceptionClassTable(java::lang::Class*) 

struct _Jv_CatchClass *catch_record = self->catch_classes;
  if (!catch_record || catch_record->classname)
    return;  

the upper to calls on the call stacks are:

#0  0x4044e484 in _Jv_linkExceptionClassTable(java::lang::Class*) (
    self=0x407b40e0) at java/lang/natClass.cc:1769
#1  0x4044caad in java::lang::Class::initializeClass() (this=0x407b40e0)
    at java/lang/natClass.cc:800

so did I screw anything up, when compiling gcj?
I did some research, but after all I think the catch_classes struct is
filled in during code generatation by the gcj compiler and, apparantly
it should never be null, or otherwise there would have been a check in 
_Jv_linkExceptionClassTable, right?

thanks for any pointers
