The ucode VM always passes 64bit integer values to sprintf implementation
while the `%d` format expects 32bit integers on 32bit platforms, leading
to incorrect formatting results.
Temporarily solve the issue by casting the numeric argument to int until
a more thorough fix arrives with the next update.
