>Description:
	The g++ compiler crashes when using the -ax option, e.g.:
	g++ -ax filename.cpp
	
	Output of compiler is:
	try.cpp: In function `int main()':
	try.cpp:3: Unrecognizable insn:
	(call_insn 46 45 47 (call (mem:QI (symbol_ref ("__bb_trace_ret")) 0)
			             (const_int 0 [0x0])) -1 (nil)
	     (nil)
	         (nil))
	try.cpp:3: Internal compiler error in extract_insn, at recog.c:2218
	Please submit a full bug report,
	with preprocessed source if appropriate.
	See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
    
>How-To-Repeat:
	Edit a very simple cpp file, e.g. with only one line of code: 
	int main () {};
	Compile the file with the following command:
	g++ -ax filename.cpp
>Fix:
	Work around : omit -ax option.
