Searching through the dumped files, I found (after reduction) this
problem:

>(funcall (compile nil '(lambda () (declare (optimize safety)) (ldb (byte 13 
13) 43710))))

Compiling gazonk9.lsp.
End of Pass 1.
End of Pass 2.
OPTIMIZE levels: Safety=0 (No runtime error checking), Space=0, Speed=3
Finished compiling gazonk9.lsp.
Loading gazonk9.o
start address -T 0x8519120 Finished loading gazonk9.o
Error in COMPILER::CMP-ANON [or a callee]: The function COMPILER::LDB1 is 
undefined.


For some reason it was not immediately detecting this problem, but
instead got corrupted and crashed ~160 iterations later.
