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:
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.
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.
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.
