crash in Java_sun_awt_X11_XToolkit_getNumberOfButtonsImpl on solaris-sparcv9

[Christian Thalinger]

While testing one of my changes with CompileTheWorld I hit a problem:

CompileTheWorld (1411) : com/sun/java/swing/plaf/motif/ 
MotifInternalFrameTitlePane$Title

========================================================================
Unexpected Error
------------------------------------------------------------------------------
SIGBUS (0xa) at pc=0xffffffff76c05264, pid=20849, tid=1

Do you want to debug the problem?

To debug, run 'dbx - 20849'; then switch to thread 1
Enter 'yes' to launch dbx automatically (PATH must include dbx)
Otherwise, press RETURN to abort...

The debugger shows that it seems to be a problem in getNumButtons:

   ---- called from signal handler with signal 10 (SIGBUS) ------
   [10] XListInputDevices(0x10118d0d0, 0xffffffff7fffb710, 0x1,

   [12] Java_sun_awt_X11_XToolkit_getNumberOfButtonsImpl(env = , cls  
= ) (optimized), at 0xffffffff77c1da34 (line ~925) in "XToolkit.c"

Is this a known issue?  I couldn't find anything related in Bugster  
but it also could be a VM problem.
