What makes you think this is a problem with ELDK's C++ compiler?  Did
you for example try to compile the same program with a native GCC 3.x
C++ compiler on your PC?

I agree with your rating ;-)

This program cannot be compiled, there is a '}' missing.

This was most definitely NOT the command line you used.

What makes you think so? I bet a case of beer that the 'new" returned
just fine, and that your program segfaulted in memset() instead.

Of course you didn't see this, as your test if p is NULL is much  too
late,  and  obviously  you  didn't  bother to run the program under a
debugger.

There are no known C++ problems specific to the ELDK  (i.  e.  except
those that apply to the native version of the same GCC as well).

The problem is not with the ELDK.
