On Windows the function does not have a symbol associated with it:
Function: id = {0x000001c9}, name = "_Dfunction", range =
[0x0000000140001000-0x0000000140001004)
LineEntry: <...>
Whereas it does on Linux:
Function: id = {0x00000023}, name = "_Dfunction", range =
[0x0000000000000734-0x0000000000000738)
LineEntry: <...>
Symbol: id = {0x00000058}, range =
[0x0000000000000734-0x0000000000000738), name="_Dfunction"
This means that frame.symbol is not valid on Windows.
However, frame.function is valid and it also has a "mangled" attribute.
So I've updated the test to check the symbol if we've got it, and the function
always.
In both cases we check that mangled is empty (meaning it has not been treated
as mangled) and that the display name matches the original symbol name.
