These are the disadvantages of alloca in comparison with
malloc:
-
If you try to allocate more storage 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 section 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.
