Debugger received error of type: DIVISION-BY-ZERO #<a DIVISION-BY-ZERO 0x7f8925037640> Error flushed.

gcl, sbcl and ccl all return #C(-1.0 0.0).

Probably related. (log #c(0 1)) and (log #c(0 -1)) both signal a division by zero.  The answer should be #c(0 1.5707964) and #c(0 -1.5707964), respectively.
