Ill-sorted injection casues unpredicatable behavior

[tothtamas28]

Consider

// test.k
module TEST
endmoule

and

// input.kore
Lbl'-LT-'generatedTop'-GT-'{}(
    Lbl'-LT-'k'-GT-'{}(
        kseq{}(
            inj{SortBool{}, SortKItem{}}(\dv{SortBool{}}("false")),
            dotk{}()
        )
    ),
    Lbl'-LT-'generatedCounter'-GT-'{}(
        \dv{SortInt{}}("0")
    )
)

When running this program:

$ test-kompiled/interpreter input.kore 0 /dev/stdout

the result is as expected:

Lbl'-LT-'generatedTop'-GT-'{}(Lbl'-LT-'k'-GT-'{}(kseq{}(inj{SortBool{}, SortKItem{}}(\dv{SortBool{}}("false")),dotk{}())),Lbl'-LT-'generatedCounter'-GT-'{}(\dv{SortInt{}}("0")))

However, changing the From-sort of the injection to SortInt{} sometimes causes a segfault:

[1]    15017 segmentation fault (core dumped)  test-kompiled/interpreter input.kore 0 /dev/stdout

and sometimes results in successful termination with a well-sorted configuration containing a huge integer:

Lbl'-LT-'generatedTop'-GT-'{}(Lbl'-LT-'k'-GT-'{}(kseq{}(inj{SortInt{}, SortKItem{}}(\dv{SortInt{}}("<huge integer>")),dotk{}())),Lbl'-LT-'generatedCounter'-GT-'{}(\dv{SortInt{}}("0")))

When the From-sort is SortBytes{} (requires importing BYTES-SYNTAX in TEST):

Lbl'-LT-'generatedTop'-GT-'{}(Lbl'-LT-'k'-GT-'{}(kseq{}(inj{SortBytes{}, SortKItem{}}(\dv{SortBytes{}}("\xe0\x00 *\x14\x7f\x00<repeating \x00>\x00[1]    15733 segmentation fault (core dumped)  test-kompiled/interpreter input.kore 0 /dev/stdout

This behavior is not robust and is potentially insecure. Ideally, the interpreter should exit with an error message.
