No, it crashes for a different reason.
The first bug occurs if you use pre-increment/decrement with a potential environment variable, such as
++myvar. It does not occur in v2, which handles variables the same as if #NoEnv was in effect.
The second bug occurs if you use
throw, because of
an erroneous line that was added by automatic merge with v1. The heap is corrupted by
throw, but you may not see the effect immediately.
There is a third bug relating to the first one which affects v1 and v2. If you use
++MyClass.x with #Warn, you will get a warning because ++ only looks to the next token for its target variable. Fixing this means
delaying the check to a later stage, which incidentally also fixes the first bug.
