<pre>A static local variable usually has its DWARF entry emitted as a child
of the defining DIE for its subprogram.
But if the subprogram is inside a namespace, the variable’s DIE gets
emitted as a child of a non-defining declaration DIE for the subprogram.
This makes it inaccessible to gdb.
Run the following program under gdb. When you step into Test::NSFunc(),
“info locals” reports no locals and “p foo” says there’s no such variable.
Step into GlobalFunc() and you can see “bar” just fine.
namespace Test {
void NSFunc() {
static int foo = 1;
foo++;
}
}
void GlobalFunc() {
static int bar = 1;
bar++;
}
int main(void) {
Test::NSFunc();
GlobalFunc();
return 0;
}</pre>
