Content
Proposed patch makes const folding more safe by checking arguments before doing expensive calculation that can create large object (multiplication, power and left shift). It fixes examples in this issue, issue21074, issue30293. The limit for repetition is increase from 20 to 256. There are no limits for addition/concatenation and like, since it is hard to create really large objects with these operations.
