I wasn't able to reproduce the first problem you reported.  But I was 
able to eventually reproduce the problem with the second example.  I 
configured gcc using
CFLAGS="long string of options" CXXFLAGS="long string of options" 
../gcc/configure ...
where "long string of options" came from your message.  When I built gcc 
this way, your new[-1] example did fail.  Unfortunately, -g was not in 
your list of options, so I was unable to debug the result.

I never did get the first example to fail.

At this point, I've spent about as much time on this as I care to.  I 
suggest filing a bug report, or trying to debug this yourself.  If you 
file a bug report, be sure to include enough info for someone else to 
reproduce the problem.  If the problem is that libsupc++ has 
dependencies on being compiled with a frame pointer, then maybe 
something as simple as adding -fno-omit-frame-pointer to CFLAGS in the 
libsupc++ Makefile would solve the problem.
