These are the disadvantages of
alloca in comparison with
- If you try to allocate more memory than the machine can provide, you
don’t get a clean error message. Instead you get a fatal signal like
the one you would get from an infinite recursion; probably a
segmentation violation (see Program Error Signals).
- Some non-GNU systems fail to support
alloca, so it is less
portable. However, a slower emulation of
alloca written in C
is available for use on systems with this deficiency.
