--- Comment #5 from Rich Felker <bugdal at aerifal dot cx> --- I reopened this, but now that I'm reporting a new symptom that's independent of the original symptom, I'm wondering whether I should file a separate bug report for it, or continue the issue under this original report. Which way is best? Both have the same fix (removing the invalid optimization or replacing it with a valid one), but the user-visible erroneous behaviors are distinct.
