A bit more logs could be useful. Internal compiler error is by 
definition a serious GCC bug, not our fault. If it happens with recent 
GCC, it deserves reporting to GCC. If it's easy to work around, I can 
put it in, but in this case GCC is not even giving a hint about 
suspicious area (unless it's earlier in logs, but I think it would 
usually be in the same line as "Segmentation fault").


To investigate it further, a preprocessed file would be useful. Gecko 
has makefile rules that make it easy. You can get that with:

make PresentationCallbacks.i -C path/to/wine_gecko/build/dom/presentation/

It should be enough to experiment further without doing whole Gecko 
builds. Please send PresentationCallbacks.i together with the command 
that will be executed. I will see if I can somehow reproduce the problem 
with it.


Thanks,
