>Description:
Compiling the following code that attempts to mix intrinsics with an operator function causes g++ to crash with a segmentation fault:

class v8qi
{
   operator int __attribute__ ((mode(V8QI))) () { }
};


% g++ -mmmx -march=athlon test.cpp
test.cpp:3: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.

Note that the -mmmx and -march=athlon options are not required for it to crash.
>How-To-Repeat:
Compile with the command line described.
