More serious : sage -t --long --warn-long 30.0

src/sage/libs/gap/element.pyx # Killed due to segmentation fault 

This is reproducible. according to test.log, the last test to be 
successfully executed is 
sage: s = libgap.Sum sage: s(libgap([1,2])) 3 sage: s(libgap(1), libgap(2)) 
Traceback (most recent call last): ... GAPError: Error, no method found! 
Error, no 1st choice method found for `SumOp' on 2 arguments sage: for i in 
range(100): ....: rnd = [ randint(-10,10) for i in range(randint(0,7)) ] 
....: # compute the sum in GAP ....: _ = libgap.Sum(rnd) ....: try: ....: 
libgap.Sum(*rnd) ....: print('This should have triggered a ValueError') 
....: print('because Sum needs a list as argument') ....: except 
ValueError: ....: pass 

and the crash could have been created by :
sage: libgap_exec = libgap.eval("Exec") sage: libgap_exec('echo hello from 
the shell') hello from the shell
