 This means the patch isn't the problem, it is the solution. The patch
 mentioned is in 3.3 and 3.3 is fine, it is not yet in 3.2 but it should
 be.

 Hi,
 
 this is a 3.2 regression that is fixed in 3.3 most likely by this change:
 --------------------------------------------------------------------------
 revision 1.336
 date: 2002/10/15 22:03:53;  author: jason;  state: Exp;  lines: +22 -4
         * call.c (call_builtin_trap): New fn.
         (convert_arg_to_ellipsis): Use it.  Downgrade error to warning.
         (build_call): Don't set current_function_returns_abnormally outside
         a function.
 --------------------------------------------------------------------------
 The interesting bit is the build_call change because the testcase
 crashes in this piece of code (current_function_returns_abnormally is
 a macro that unconditionally deref cfun):
 
   if (decl && TREE_THIS_VOLATILE (decl))
     current_function_returns_abnormally = 1;
 
 Since revison 1.336 this code reads
 
   if (decl && TREE_THIS_VOLATILE (decl) && cfun)
     current_function_returns_abnormally = 1;
 
 
     regards   Christian
