[Bug c/41942] New: __attribute__ ((visibility)) weird with functions returning pointers

Wed, 04 Nov 2009 10:30:54 -0800 

const char * __attribute__ ((visibility ("hidden"))) foo(void)
{ return "foo"; }

const char __attribute__ ((visibility ("hidden"))) * bar(void)
{ return "bar"; }


Compile this with:

gcc -fPIC -Wl,--version-script=foobar.map -Wl,--strip-all -shared -o foobar.so
foobar.c

foo() now issues the warning "warning: ‘visibility’ attribute ignored on
non-class types" and the visibility is not applied. Placing the attribute at
that position is very unintuitive and the warning isn't particular helpful.
Also I found nothing in the documentation about this.
