Bug ID: 88442
Summary: Misleading error message with duplicated struct
definitions
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: a...@linux-foundation.org
Target Milestone: ---
q:/home/akpm> cat t.c
struct foo;
struct foo { int a; };
struct foo { int a, b; };
q:/home/akpm> gcc -c t.c
t.c:5:8: error: redefinition of 'struct foo'
struct foo { int a, b; };
^~~
t.c:1:8: note: originally defined here
struct foo;
It's arguably misleading and certainly unuseful to say that struct foo was
originally defined at line 1. You sit there scratching your head looking at
line 1 wondering why it didn't compile. It would be more useful to point the
user at line 3!
