"inline" causes assertion failure "functor type not set"

Hi,

The following program meets assertion failure:

I run it with souffle -w example.dl, and the output is:

souffle: /souffle/src/ast/analysis/typesystem/Type.cpp:309: souffle::FunctorOp souffle::ast::analysis::TypeAnalysis::getPolymorphicOperator(const souffle::ast::IntrinsicFunctor&) const: Assertion `hasValidTypeInfo(inf) && "functor type not set"' failed.

If I remove the inline keyword of uzdp, the program can execute correctly. I use the last release version of Souffle.

Hi,

I reduce this test case:

.decl a(b:unsigned)
.decl h(c:unsigned, d:unsigned) inline
.decl i(c:unsigned) 

a(0).

h(d, d) :- a(d).
i(min(max(c,c),8)) :- h(c, 8).

.output i

I guess it's probably because the inline subgoal contains constants.

[DerZc]

I am not sure about the reason, because I find this test case also can trigger the bug:

.decl a(x:unsigned) inline
.decl b(x:unsigned)

a(0).
b(max(max(x,0),0)) :- a(x).

.output b

[quentin]

There is no valid overload for max(unsigned, number) in max(x,0) because 0 is a signed number.

Either replace all literals 0 by 0u, or make x a number.

Souffle should not crash/raise an assertion. It should report that there is no valid overload.
