From: bernie@codewiz.org To: gcc-gnats@gcc.gnu.org Subject: c++/6894: lookup of anonymous structure members does not work as in C frontend Date: Sat, 01 Jun 2002 06:36:00 -0000 [thread overview] Message-ID: <20020601132748.17017.qmail@sources.redhat.com> (raw) >Number: 6894 >Category: c++ >Synopsis: lookup of anonymous structure members does not work as in C frontend >Confidential: no >Severity: serious >Priority: medium >Responsible: unassigned >State: open >Class: rejects-legal >Submitter-Id: net >Arrival-Date: Sat Jun 01 06:36:01 PDT 2002 >Closed-Date: >Last-Modified: >Originator: bernie@codewiz.org >Release: gcc-3.1 >Organization: >Environment: Linux x86 >Description: The C frontend has the unnamed fields extension to allow class-like inheritance by putting an unnamed structure (the base class) as the first field of another structure (the derivate class). The C++ frontend does not reject unnamed fields, but fails to lookup fields contained within the unnamed structure, making this feature useless. >How-To-Repeat: Compile this test case with g++: #include <stdio.h> int main(void) { struct Foo { int a; }; struct Bar { struct Foo; }; Bar bar; printf("bar.a = %d", bar.a); return 0; } The reported error is: foo.cpp:7: `struct main()::Bar' has no member named `a' >Fix: >Release-Note: >Audit-Trail: >Unformatted:
