According to 7.3.2/4
"A namespace-name or namespace-alias shall not be declared as the name of any
other entity in the same declarative region. A namespace-name defined at global
scope shall not be declared as the name of any other entity in any global scope
of the program. No diagnostic is required for a violation of this rule by
declarations in different translation units."
the following c++ is ill-formed:
namespace m
{
}
namespace n
{
namespace m
{
}
}
namespace m = n::m;

Confirmed. In fact, I get ICEs with newer versions of gcc with your code:
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc
x.cc:12: redefinition of `m'
x.cc:2: `m' previously declared here
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc
x.cc:12: error: redefinition of `m'

The ICEs are a regression, as is the fact that we now don't even get to see
the original error message any more.

Not sure about ICE; for me both gcc-3.4.0 and gcc-3.4.1 compile code above
without any diagnostic.

That is most likely because Wolfgang has checking turned on. So this is ice-on-invalid-code, ICE-
checking (which means it ICE only when checking is turned on) and accepts-invalid.

My versions are also a few days old already:
gcc version 3.4.1 20040612 (prerelease)
gcc version 3.5.0 20040628 (experimental)
I guess it's time to update again.
