Bug ID: 90291
Summary: [7/8 Regression] Inline namespace erroneously extends
another namespace
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: igusarov at mail dot ru
Target Milestone: ---
Compilation of the following code with gcc 7.x and 8.x produces different
results:
inline namespace A
{
inline namesapce B // (1)
{
void foo() {}
}
}
inline namespace B // (2)
{
inline namesapce A
{
void foo() {}
}
}
If compiled with "gcc-7.4 -std=c++11 -c", the object file contains functions
A::B::foo()
B::A::foo()
which I believe is correct.
However, if the same source is compiled with "gcc-8.3 -std=c++11 -c", the
object file contains functions
A::B::foo()
A::B::A::foo()
which I believe is wrong.
It looks like gcc 8.x assumes that the namespace at line (2) doesn't start a
new top-level namespace, but extends the namespace defined at line (1).
