I write applications with lots of allocations and deallocations and
never had any problems. With good planning I can guarantee that
fragmentation will not make the application fail.

Most systems could be designed not to use dynamic allocation, but it is
much easier and flexible (and portable) with it. Why struggle with hard
to understand code, defining lots of unions if you can just allocate
some memory.

Sometimes it is just not possible to predetermine how many of what
structures you are going to need in every scenario. With unions of
overlapped structures you must have this knowledge at design time.

If there is not enough memory, then your application would fail anyway.
One must be careful enough to make the application recover gracefully
from such failure.
