It is virtually outlawed by embedded software systems where high
performance, reliability, and real time deadlines are critical. Use
of the data heap or any other dynamic memory usage is one of the code
inspection checklist items we always check. The Ada83 & operator
for strings used to get/(bite) us in the 80's with some compilers.
Functions returning complicated records (which are not inlined) also
tend to cause problems with the heap memory deallocation when using
multiple tasks. Various Ada compilers/Real Time Executives can vary
in how well they handle this.
Newmonics of Ames, IA has some very ambitious goals for
predictatable garbage collection with Real Time Java. I'm interested
in seeing just how well their implementation works out
