Problem
In the following scenario:
Account 1's discriminator starts with 0
Account 2's discriminator is a 1-byte custom discriminator
Account 2 gets initialized using the
zeroconstraint:It's possible to pass an already initialized Account 1 to a place that expects non-initialized Account 2, because the first byte of Account 1 is also 0, which is what the
zeroconstraint checks.Summary of changes
Disallow account discriminators that can conflict with the
zeroconstraint.
