What exactly (if you can say) is ~32mb in size?
It's been assumed that a user would increase memory by specifying:
-M <size>
(off the top of my head). The default being based on on whats needed by
GCC/GDB's testsuite (ignoring java) (it does contain some not too small
programs). So making it bigger is a notable tradeoff (but it has been
creaping up over time).
PSIM, for instance, avoided the problem by using OS emulation - it
models a heap and stack - so can handle [UN*X] programs of any size.
