/* Regression test for bug in convoluted situation involving token paste plus function-like macros used outside function context. It may be easier to understand if you mentally replace 'struct' with 'A' throughout this file; 'struct' is used only to get the code to compile when preprocessed correctly. The original problem was seen in the Linux kernel and reported by Jakub Jelinek <jakub@redhat.com>; this test is synthetic. */ /* { dg-do compile } */ #define glue(a,b) a##b #define struct(x) B(x) #define E(x) struct x #define FG (22) extern void B(int); void foo(void) { E(glue(F,*)) dummy; /* { dg-error "valid preprocessing token" } */ E(glue(F,G)) ; }
