Re: Debugging 64bit xemacs (beta, latest cvs) on sparc64 (Sun T1000)
Ar an triochadú lá de mí na Samhain, scríobh Andrew Walrond:
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.
Or endian-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:
Thank you for it!
Nothing comes to mind as a likely source of the problem; memcpy shouldn’t
have alignment restrictions. The crash takes place during a call of the Lisp
function command-error: if you do an xemacs -vanilla , then evaluate
(command-error (cons 'quit "Hi there"))
in *scratch*, do you see it?
