Comment (by jipmoors):

 The only way to surface the type max size problem is to check for it and
 fail when it exceeds the limit.

 PHP_INT_SIZE will hold the maximum size an Integer can have for each
 system. Silently converting/normalizing and moving on will cause unwanted
 and obscure problems. Breaking and notifying about the problem makes it
 something that can be reasoned about and a resolution to be implemented.
