!nim c

var x: int8
x = 256
echo x

from nim.

metagn avatar metagn commented on June 2, 2024 1

Maybe caused by the new type inference? (the type of 256 is changed from int literal to int8 without any checks)

Edit: changeType with check=true is called but maybe this doesn't account for int8

from nim.

Errors as intended in 1.6.16 but works in 1.6.18

from nim.
