So, at least with linux's glibc and gcc, alloca never fails. Never.

That's (sort of) documented, look into the output of

info libc "Disadvantages of Alloca"

   These are the disadvantages of `alloca' in comparison with `malloc':

   * 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 (*note Program Error Signals::).
