 I suppose it's *not* a "Internal compiler error: Segmentation fault".
 Did I get you rught?

 I just tried gcc 3.2 on your sources, but I only get an ICE.
 However, since you haven't provided a preprocessed source, I'm probably
 compiling different code than you.
 
 Can you generate a preprocessed source that also causes a segfault?
 If yes, could you please send the preprocessed file?
 
 If no, then something strange is happening :-(
 My first wild guess would be that the compiler ran out of memory when
 compiling your source. Can you make sure that this is not the reason
 (i.e. by using a swap device that is large enough)?
 You might have hardware problems: for example faulty memory (you could
 try to swap your chips if you have multiple banks of memory). I remember
 one PR where a faulty BIOS was responsible for strange gcc errors
 (are BIOS upgrades available for your board).
 
 Good luck,
 Volker
