Are you looking for someone to fix this problem for you or are you looking to learn about debugging GCC? The former will likely involve getting a volunteer or hire somebody to develop this transformation for you.
If you are interested in debugging and developing this yourself, you could start browsing the GCC wiki, there's a section with tips about debugging GCC: http://gcc.gnu.org/wiki/DebuggingGCC. In this case, it seems like you are using 4.0 and some pass is trying to get an annotation from a non-decl tree node. Set up a breakpoint and examine the backtrace to see what pass is doing this (probably yours). Perhaps you are creating a new DECL and not adding it to the list of referenced variables.
