[Sbcl-devel] Started getting memory fault in core dumps?

[Jeff C. <je...@jk...>]

Hi;

On a machine I have running Ubuntu 64-bit I keep an SBCL core dump of a
LAN web server which is set up with a cron to launch in the event the
machine is restarted. A few weeks ago I installed 10.10 beta Ubuntu
Maverick on the machine, built a fresh copy of SBCL, rebuilt the core
and dumped it. It worked fine. 

Yesterday, I did an "apt-get upgrade" to upgrade a number of libraries
that were causing problems in some other applications. When I restarted
the machine the webserver core didn't restart, giving this error
message:


        Starting servers
        CORRUPTION WARNING in SBCL pid 1129(tid 140737353971456):
        Memory fault at ae03e000 (pc=0x1000b80955, sp=0x7ffff4c726a0)
        The integrity of this image is possibly compromised.
        Continuing with fingers crossed.
        Error: Problem running initialization hook #<FUNCTION
        WEBSERVER::START-THE-SERVERS>:
          Unhandled memory fault at #x2AAAAE03E000.
        

Thinking that one of the basic libraries must have been updated, I
checked out the latest SBCL, rebuilt it, and rebuilt all my fasl's
before building the webserver core again. But it made no difference. 

Now I don't know what to do. I can start emacs and slime, hand compile
the webserver and it runs just fine. But when I attempt to dump the core
then start it, I get exactly the same error message above each time. 

Any ideas?
