>Description:
The basic_string<> class uses asm() in its release() method
for the Rep structure.  This causes a compilation error
when compiling with the GCC -fcheck-memory-usage option.
>How-To-Repeat:
Compile the above program with the option -fcheck-memory-usage.
>Fix:
I could discover no easy workaround.  I would assume that
it would be possible to move the asm() statement in this
function to another file and mark that with
__attribute__ ((no_check_memory_usage)), but I don't know
anything about x86 assembly language.

iostream.h and stl_alloc.h also have assembly language in them.
