No, exactly the reverse, when gcc makes use of this option *then* you get
problems :-D. If your gcc version really doesn't support it, you're on the
safe side.

-fvtable-gc is the only virtual method calling implementation that worked
for me under ecos (other methods seemed to generate null pointers to the
v-functions). So I guess this is a concern!

[ECOS] how to direct printf to the serial console

I am running the assabet, the debugger is working, but is there any way 
to direct the printf statements to the serial console?  so I can load 
the image from redboot and run it from serial console and it shows me 
the printf statements? without the debugger.


thanks

-fvtable-gc shouldn't change the way virtual methods are called, it's
supposed to throw away method implementations that are *not* called. But
it looks like it sometimes throws away more than it should.

Patrick: Which gcc are you using? IIRC, the option was removed for gcc
3.0 and the re-added later on.
