What does this fix? Isn't it just hiding potential bugs?

PS6, Line 9: Initialize register size variables to prevent segfaults.
If the program would read those variables on a broken path (only chance
for a segfault), the only thing we achieve with these initializations is
hiding bugs.

why initialize one arg but not the other?
