Subject: [Bug c++/62202] New: g++ does not accept typedef-name after struct even if -fpermissive is used
Date: Wed, 20 Aug 2014 12:36:00 -0000 [thread overview]
Message-ID: <bug-62202-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62202
Bug ID: 62202
Summary: g++ does not accept typedef-name after struct even if
-fpermissive is used
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bugzilla@poradnik-webmastera.com
gcc silently compiles this, even with -Wall -Wextra -pedantic:
struct test_s { int n; };
typedef struct test_s test_t;
typedef struct test_t* something_t;
int main() { return 0; }
g++ reports following error even if -fpermissive option is used:
test.c:3:16: error: using typedef-name ‘test_t’ after ‘struct’
typedef struct test_t* something_t;
^
test.c:2:23: note: ‘test_t’ has a previous declaration here
typedef struct test_s test_t;
^
test.c:3:35: error: invalid type in declaration before ‘;’ token
typedef struct test_t* something_t;
^
Please extend permissive mode to accept such case too. Also consider printing
warning when compiling C code.
