Comment 1 David Schleef 2006-03-06 17:37:43 UTC 
I just noticed that you're using -march=pentium4.  That explains why I was never
able to reproduce this bug.  Please remove the flag and try again.
Comment 2 Mikhail Zabaluev 2006-03-07 10:03:39 UTC 
It doesn't fail anymore on 0.3.7, even with -march=pentium4.
