It's hard for me to fix bugs without being able to reproduce it.

But you can help me by compiling older development version to try to 
find the revision number where it starts to fail.

$ svn checkout -r REVISION ...

I know it's very long to recompile older version, but I don't have 
better at the moment...

The revision number I'd like you to test are (in that order): 6754, 
6693, 6681.
