I've reported 3 Oops'es in this mailinglist with 2.2.3. Two of them
happened with an invalid file pointer and the third one was much
later, perhaps as a result of the previous two Oopses. I compiled with
gcc-2.7.2
The subject of my mail was: 3 Ooopses in 2.2.3
Here the facts (of the first oops) again:
