[Faré]

Package: cmucl
Version: 19d-20061116-1
Severity: normal

*** Please type your report below this line ***
Since I last upgraded cmucl, I get the following error and backtrace
whenever I start it.

$ cmucl

   [Condition of type SIMPLE-ERROR]

Interestingly, if I run cmucl -noinit, I get no such error.
However, I have no initialization file, as far as I can tell: neither of
  ~/init.lisp
  ~/.cmucl-init.lisp
exists
And strace fails on cmucl after the first memory-management-related segfault
so I don't know what's going on.

Also interestingly, if another user starts cmucl, it works.
If same user starts with a different $HOME, it also fails.
If another user with essentially the same config starts it, it works.
It used to all work fine.
Failure 100% reproducible in my current environment.
I'm baffled.
