Debugging 64bit xemacs (beta, latest cvs) on sparc64 (Sun T1000)

Hello list, I have a nice little pure 64bit distro running on a sun T1 (niagra) box. Everything builds and runs fine, except xemacs, which crashes every 30secs or so. Using exact same distro and xemacs build running pure 64bit on x86_64 boxes does _not_ show the same problems, so this is likely something sparc64 specific. Anyhow, to diagnose the problem I have downloaded (cvs) and built the latest beta version and installed the sumo tarball. I enabled core dumps, loaded up some kernel sources into xemacs and started playing around, splitting windows and scrolling about. Sure enough, I soon got a segfault, and here is the backtrace: $ gdb /bin/xemacs /tmp/core GNU gdb 6.5 Copyright (C) 2006 Free Software Foundation, Inc.

I can test, and give ssh access to the server if that would help.
