Thank you Juanjo.


How did you track the problem down? I've tried, but found it very hard to debug 
the issue. In theory one should be able to tie it down to a function I believe, 
but I was unable to.

Is it possible you could show me the code changes that were made. If possible, 
it would be nice to produce a small test case which exhibits this problem, then 
submit that as a gcc bug.
