The code below gives the following error:
internal compiler error: tree check: expected class type, have exceptional (error_mark) in 
build_pointer_type_for_mode, at tree.c:4246
    This sounds like bug 18177, but that was supposedly fixed in 4.0.0.
    PalmSource bug 105393.

Here's the code:
typedef int32_t (*ProcPtr)();void Dispatcher(int32_t startCode)   (__builtin_offsetof (ArgsType, 
largeMsgLen) + sizeof(Args.largeMsgLen)))

    "__builtin_offsetof" is necessary for the crash, and is an artifact of preprocessing.  This is a Delta-
reduction of a larger file which fails without error under g++ 3.3.4, presumably correctly, due to a 
missing include file.

Confirmed, a little further reduced:
void Dispatcher()
 (__builtin_offsetof (ArgsType, largeMsgLen))



Even changing __builtin_offsetof to __offsetof does not make 3.4.0 ICE.

 This doesn't ice with the C frontend.  However, it does with the C++ frontend
with a recent build of mainline.

 Having build_pointer_type_for_mode return error_mark_node when it is passed
error_mark_node seems to fix this.

: Search converges between 2004-06-01-trunk (#459) and 2004-06-02-trunk (#460).


Looks like when __builtin_offsetof was added :(.
