 BTW, the synopsis in 8081 is quite unspecific (so it's hard to find
 that report when looking for it). Can it be changed?
 
 The variable sized return type seems to be the crucial thing; nested
 functions are not directly related (just necessary to evoke the
 problem because GCC won't allow variable sized types outside of
 functions).

Calling a function with variable sized return type causes an
internal compiler error.

  f ();  /* GCC crashes here */
  return 0;
