A few other __attribute__ bugs:



$ sed -i s/warning/weakref/ bug.c

$ gcc -S bug.c

bug.c:1:1: error: attribute 'alias' argument not a string

 extern void foo(void) __attribute__((weakref(0)));

 ^

bug.c:1:13: warning: 'weakref' attribute should be accompanied with an 'alias'

attribute [-Wattributes]

 extern void foo(void) __attribute__((weakref(0)));

             ^

$ sed -i s/weakref/section/ bug.c

$ gcc -S bug.c

bug.c:1:13: error: section attribute not allowed for 'foo'

 extern void foo(void) __attribute__((section(0)));

             ^

$ echo 'void *foo(int) __attribute__((alloc_size("1")));' > 1.c

$ gcc -S 1.c

1.c:1:1: warning: alloc_size parameter outside range [-Wattributes]

 void *foo(int) __attribute__((alloc_size("1")));
