Another test case:
void a();
namespace b {
using ::a;
}
namespace c {
template void a();
template void f(d, e) {
using b::a;
using c::a;
}
template void i(g j, h, e k) { f(j, k); }

I spent a good chunk of today to debug. The culprit was two variables that had
not been set equal to 0. I get the same results with g77 on Windows, GFortran

I've also noticed some incorrect compiler errors when trying to default

I am not sure where the -g -O2 -g0 comes from. I must have missed this in my

The issue is the .file 0 directive, which is special to gas (only valid with

Ah, no, the *.s file is generated with -g, but the assembler isn't able to cope
with it.
I'd say that the assembler shouldn't require any directive or flag but just
assemble it.

The assembler has all the information in the assembly, .debug_info section
contains version etc.

I'd be for automatic bumping to dwarf5 level if .file 0 is seen, but remember
that it happened and issue an error if .debug_info with version older than 5 is
seen in the file.

On the binutils gas side it could be as simple as turning the error into a

But then it will warn and not do what it was expected to do.
