Splitting debugger in two - specific debugger and common GUI

Can you try to debug the Chinese symbols, I can't reproduce it on linux here and I don't know when I'll have time to switch to windows?

I just tested, and if the project path has spaces, then it will show some "Unknown Chinese characters".
This is because gdb can not handle path with spaces.
If you do not have spaces in your path, but no exe built, then there is not such Chinese symbols.
The debugger freeze in both cases. I'm testing latest debugger branch nightly build.
PS, you can not set a breakpoint in a file with spaces under gdb(Windows).

Yes, I am already at it but face two times another freeze bug (the one reported earlier with "out of function scope")... :-(

This works very well for me if you have set the "GDB workaround in the advanced compiler options.
MortenMacFly:
OK - when entering "GDB_driver::GetCommandLine(const wxString& debugger, const wxString& debuggee, const wxString &userArguments)" I see that "debuggee" is exactly "" " (quote, space). This looks pretty weird.
I see in the debug log:
[debug]> output debuggee
[debug](const wxString &) @0x22e200: {
[debug] <wxStringBase> = {
[debug] static npos = <optimized out>,
[debug] m_pchData = 0x17f39544 L"\"\xe920\221\174"
[debug] }, <No data fields>}>>>>>>cb_gdb:
(I'll update this post if I got news...)
EDIT: UPDATE:
A little earlier (in int DebuggerGDB::DoDebug(bool breakOnEntry)) I see that "path" is "C:\\Dokumente und Einstellungen\\Morten\\Desktop\\MyCon2\\." then after a call to "ConvertToGDBDirectory(path)" it is "C:/DOKUME~1/Morten/Desktop/MyCon2/.". That's OK.
The command line generated in in "GDB_driver::GetCommandLine" uses "-args " ", so the final command line is:
C:\\Devel\\GCC46TDM\\bin\\gdb.exe -nx -fullname -quiet -args "
Do you see the trailing single quotation mark? I think that's it. A bug. :-)
-> No closing quotation mark, so the debugger reads garbage!

I have already have this option checked.
