What SLIME's backtrace is showing here is part of the process of calling
out to lisp after the lisp kernel has detected an exception (an invalid
memory access of some sort.)  That isn't very interesting; the next
few older frames would (hopefully) show us something about what was
happening when the fault happened.

? (rebuild-ccl :clean t)

will delete all FASL (.wx32fsl) files in the CCL hierarchy, compile
all sources into fasls, and rebuild the heap image.

On other platforms, other arguments to REBUILD-CCL will also cause
the lisp kernel (C and assembler code) to be rebuilt.  Unfortunately,
Windows doesn't allow an executable file (wx86cl.exe) to be overwritten
while it's running, since that would be too useful.
