>From tree-inline.c:

          case BUILT_IN_LONGJMP:
            /* We can't inline functions that call __builtin_longjmp at
               all.  The non-local goto machinery really requires the
               destination be in a different function.  If we allow the
               function calling __builtin_longjmp to be inlined into the
               function calling __builtin_setjmp, Things will Go Awry.  */

so IMHO we shouldn't inline foo ().  See inline_forbidden_p_stmt.
