I build libgcj with "--enable-threads=posix" option.
The problem is still there.  Here is the stack trace:
(gdb) bt
#0  0xef6e7820 in _CL_Q34java4util4Date () from
/usr/local/lib/libgcj.so.1
#1  0x1647c in printLineFromJava () at CCJava.cc:10

../../../../source/libgcj-snapshot-2000-07-07/libjava/posix-threads.cc:344

But, I found the way to work arround.  I remove
'virtual' keyword from the prototype for
::JavaTool::printLine().  Here is the change:

class ::JavaTool : public ::java::lang::Object
{
public:
  //virtual void printLine (); -- generated by gcjh
  void printLine();
  JavaTool ();
};

What do you think?  Is it an issue in gcjh or gcj?

Thanks,
Cecilia
