It looks like the some CI jobs are failing on

thread 'rustc' panicked at src/int.rs:176:13:assertion failed: a_type.dyncast_array().is_some()

which is some code I didn't touch.

Can my changes have some side effects ?
I see that#631 also have these jobs failing. Perhaps it's not my changes which bring these failures.

Any hints ?

Not sure it's related. I opened a new dummyPR to check if the tests pass, though.

TheCI passed, so the problem is in here.

I suspect this is because you changed the return type: it used to return an array type and your change makes it return au32.

The return type of theif width == 128 was already au32 because the block ended with

                let res = self.context.new_array_access(self.location, result, index);                return self.gcc_int_cast(res.to_rvalue(), result_type);

which will get an element in the array and cast it as result_type which isu32.

Edit: formatting

Ok, finally found the line pointing in my changelet leading_zeroes = self.add(low_leading_zeroes, sixty_four); wherelow_leading_zeroesandsixty_four are of different types.

The problem I see is that theif branch should have been taken.
