Hi all,
Bug Report: If winedbg is asked to load an external PDB file, and that file does not match the executable being run, the debugger does not warn about it. Instead, bad things (tm) happen when actually trying to run the executable.
Shacharcould you be more specific on the errors ?
- running with +dbghelp
- pasting the output of 'info module'
what are the 'bad things' you're talking about ?
A+
I'm sorry - I wrote this email in a hurry, so I don't forget of the problem's existance. Will give more details a bit later.

Ok, here goes: First - reconstruction instructions (Visual Studio 6, latest SP): Take any C++ project (it happens with the one generated when you ask for a sample "hello world" application). Copy the "Release" configuration over, and open the project settings. Add to the "C/C++" tab, in the "General" section, "Debug info: Program Database". In the "Link" tab, in "Debug", check "Debug info", with "Microsoft format". At this point, if you compile your project, visual studio's integrated debugger sees the debug info, and can debug the application. However, if you try to load this very same application in winedbg, it fails to load the symbols. Output pasted later on.
Next, go back to the "Link" tab, and add "Separate types". Recompile (make sure you "rebuild all"). Now winedbg can see the debug info, and works. Before the latest winedbg patch, it worked in the previous mode as well.
Sample session of showdebug/semidebug$ WINEDEBUG=+dbghelp winedbg showdebug.exe Since there is lots of cruft there, I ran it once working and once not, and am only pasting the diff between the two here. Those marked with ">" are the lines when things are working (scroll to the end to verify). The command run was "break WinMain".

Let me know if you need any more info.
(obviously, for program listing to actually work, I pointed wine's S: to where my sources reside).
