Segfault sygus-stream true, sygus-verify-subcall false, sygus-inference true

[wintered]

Hi,
For this formula:

% cvc4-d80192c --quiet bug.smt2
CVC4 suffered a segfault.
Offending address is 0x0
Looks like a NULL pointer was dereferenced.
Aborted
% cat bug.smt2
(set-option :sygus-stream true) 
(set-option :sygus-verify-subcall false)   
(set-option :sygus-inference true)   
(declare-fun x () Real)   
(assert (<= 0 0.84)) 
(assert (> (sin 238) 0.85)) 
(assert (> (- 52 x 0) 0)) 
(assert (> (/ 236 0 x) 0)) 
(check-sat)  

CVC4 throws out a segmentation fault.
