To: gcc-bugs
For an invalid code snippet like
int i;
namespace N = i;
we issue the error message
bug.cc:2: error: expected namespace-name before ';' token
bug.cc:2: error: unknown namespace '<declaration error>'
with the not very helpful '<declaration error>'.
The situation for the code snippet
int i;
using namespace i;
is similar. Here we get the error message:
bug.cc:2: error: expected namespace-name before ';' token
bug.cc:2: error: '<type error>' is not a namespace
With the old parser we got
bug.cc:2: error: unknown namespace `i'
resp.
bug.cc:2: error: namespace `i' undeclared
so this qualifies as a diagnostic regression.
I'll post a patch soon.

The problem there is twofold: The compiler fails to report which name is not a namespace-name (N2) and why (because it's ambiguous). The patch would only fix the first problem; the second would still remain. -- What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |reichelt at gcc dot gnu dot |dot org |org URL| |http://gcc.gnu.org/ml/gcc- | |patches/2005- | |08/msg01601.html Status|NEW |ASSIGNED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23586 ^ permalink raw reply [flat|nested] 9+ messages in thread
