The level argument isn't optional at all. Turning on argument count
checks would prevent such errors.
It has to be:
.sub "dump" method
.param int level :optional
Okay, thanks, changed. Joshua, let me know how it goes. Particle,
could you check and see if this fixes your problem as well?
What's the difference between :optional and :opt_flag? I found a few
lines of documentation on these once I knew what to grep for, but
that's all.
Marking optional parameters is a good move forward. But... retrieving
garbage values into parameters that aren't passed an argument is not
a good design for a stable system. It leads to thorny bugs like this
one. (I've been looking for it for over a month, but could never
reproduce it on any of my machines.) Can you prevent it from
retrieving garbage values, even when :optional isn't set?
