   2    bug-3249.c. A check for the possibility of tail-call optimization in codegen assumed that code is generated for a function (as opposed to initialization of file-scope objects),
   3    resulting in a segfault when initializing file-scope static objects in non-intrinsic named address spaces from the Embedded C standard.
