It looks like a buffer overrun in q2c.c  Can you try this patch.

Also, you shouldn't configure from within the source directory if you
have already configured from another directory, otherwise bad things 
may happen.   However it's okay to configure from two (or more)
seperate directories outside the source dir.

     linux an windows versions, so I use configure

     compile. I'm sending the diff of the two files
     one on the source folder, and other on another folder.
     Do you have any clue of why this is happening?
