Hot reloading DLL no longer works -- uses old PDB?

[karl-zylinski]

I used to be able to hot reload a video game DLL and the debugger picking up the new PDB automatically. It just worked. But now it no longer seems to load the PDB for the new DLL.

What I do is this:

• I build game.dll and game.pdb
• My host application copies game.dll to game_X.dll where X is a number
• The host application loads game_X.dll

When I step into code that uses the new DLL, then I end up at garbage debug symbols, which hints to me that it is still using the old PDB.

I investigated this a bit more, if I write the pdb with a new file each time, then it works. In the past, I think it used to somehow understand the pdb was new even when I overwrote the original one.

I tried with old versions of the debugger and couldn't get it to work with those either. I might have been dreaming that this ever worked. So I guess this is a feature request rather than a bug report now.
