As I said: The official statement regarding compiling trunk is that you 
must use the latest release to be on supported ground. If the promise of 
this statement is not kept by reality then this is a bad sign.

Of course one could try to reproduce the problem using a trunk compiler 
and then the fix could be backported to the old release.

In both cases (debugging the old one; using a trunk compiler) the target 
is to fix the old release so that a new release based on the old release 
branch (a hypothetical 2.4.6) would be able to compile trunk (or more 
importantly the next release (e.g. 2.6)) again.
