The option `allow_use_file` seems to be the problem as setting it
to False make the issue disappear.
sage: for i in range(10):
....: print(i)
....: gap.eval("D_4 := SmallGroup(8,3);;" + "IsSolvable(D_4);"*i,
allow_use_file=False)

I confirm the bug on arch. It seems to me that there is
something related to the "input length" (but nothing about the
specific commands)

Hello,
I got a report about GAP problem in SageMathCell, but it looks like
the GAP
interface in Sage itself is having issues. I am getting an empty string
from the following command:
sage: print(gap.eval("""
....: D_4 := SmallGroup(8,3);
....: IsAbelian( D_4 );
....: List( ConjugacyClasses( D_4 ), Size );
....: IsCyclic( D_4 );
....: Size( AllSubgroups( D_4 ) );
....: Size( Set( D_4, Order ) );
....: IsSolvable( D_4 );"""))
All commands work fine in GAP and even in Sage each one seems to be
working, but certain combinations of them do not, while some do - I can't
understand the system here...
Does anyone have any ideas on what is going on?
Thank you!
Andrey
