Summary: G++ fails to accept a legal struct declaration in a
namespace
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: wirawan0 at softhome dot net
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
Under certain circumstance, g++ fails to accept a legal C-style struct declaration in namespace, for example:
#include <complex> // complex is defined here, but under namespace std
namespace f2c {
typedef struct { real r, i; } complex; // *GCC SAYS ERROR
}
GCC gives the following error on the ERROR line above:
error: semicolon missing after struct declaration
error: abstract declarator `f2c::<anonymous struct>' used as declaration
error: namespace-scope anonymous aggregates must be static
Somehow this only happens when the source code is very complex. I will send you a (preprocessed) sample code that cause G++ to stumble. Or send me an email for the code if the attachment does not appear soon.

The stumbling source code
Here is the (initial part of) cc1plus output message:
GNU C++ version 3.3.1 (i686-pc-linux-gnu)
compiled by GNU C version 3.3.1.
GGC heuristics: --param ggc-min-expand=47 --param ggc-min-heapsize=32018
In file included from src/cp.inc/LAPACK_dsyevx.cpp:100,

The stumbling source line is at line 42418 of file tbhqmc-dmc.ii.
Here's the command-line (invocation of cc1plus) that's known to give the same
error (the basepath of cc1plus may vary):

The exact same problem also appears on g++ version 3.2.2; here's the output string of that compiler:

TEMPORARY WORK-AROUND:
change the one line
typedef struct {real r,i;} complex;
to two lines:
struct complex { real r,i; }
typedef struct complex complex;

Did you really mean that? There is a missing semicolon.

Re: Gaby's comment
Of course not! Sorry, a typo. Yes, a `;' should be THERE.

------- Additional Comments From bangerth at dealii dot org 2003-10-16 19:10 -------
This is a reduced testcase:
-----------------------
namespace NS1 {
template <typename> struct S;
}
using namespace NS1;
namespace NS2 {
typedef struct { } S;
}
-----------------------
It fails with all gcc versions up to 3.3:
g/x> /home/bangerth/bin/gcc-3.3.2-pre/bin/c++ -c x.cc
x.cc:7: error: semicolon missing after struct declaration
x.cc:7: error: abstract declarator `NS2::<anonymous struct>' used as
declaration
x.cc:7: error: namespace-scope anonymous aggregates must be static
It succeeds to compile with present mainline, though, so it seems to be
fixed.
