+-O=all includes loop, but the interaction with the other optimizations
+makes the bug go away (I'm almost sure it's not a bug in the loop
+optimization, but it just chnages the code enough to make another bug
+show up).
+Please, try with the snapshot that works and run with:
+mono -O=loop and tell us if it works.
+Paste also the lines in mini/ChangeLog that are different: there were
+several patches on May 25, just to make sure it's really the loop and
+not any of the other stuff (which you could try to revert by
+extracting the diff and doing patch -r <diff).
