I have recently upgraded cpptools from v1.0.1 to v1.1.2. After that I am unable to set breakpoints (they are set in disabled state). I am debugging program that runs on the board with ARM processor and Linux OS (the gdbserver runs on that board). On the PC side gdb-9.2 is used. The sources are located at the PC and the executable is accessible on the target board using samba. Here is the launch.json:

{
   "version": "0.2.0",
   "configurations": [
      {
         "name": "Remote debug",
         "type": "cppdbg",
         "request": "launch",
         "program": "//192.168.122.233/share/OGL/build/main.elf",
         "miDebuggerServerAddress": "192.168.122.233:1234",
         "args": [],
         "stopAtEntry": true,
         "cwd": "${workspaceRoot}",
         "environment": [],
         "externalConsole": true,
         "sourceFileMap":{
            "/share/OGL":"${workspaceRoot}"
         },
         "windows": {
           "MIMode": "gdb",
           "miDebuggerPath": "C:\\gdb-arm-linux\\bin\\arm-linux-gnueabihf-gdb.exe",
         }
       }      
   ]
}

There is an error in the logs (see below). As you can see the file path is invalid (see second line of the log below) because of \ symbols were used (instead of /). So, the source path mapping is probably broken.

Here is the log from the 1.1.2 version, when I tried to set breakpoint (it does not work):

<--   C (setBreakpoints-13): {"command":"setBreakpoints","arguments":{"source":{"name":"test.c","path":"d:\\Oleg\\!Projects\\Neon3\\Software\\Client\\CtrlPi\\test.c","sources":[],"checksums":[]},"lines":[163],"breakpoints":[{"line":163}],"sourceModified":false},"type":"request","seq":13}

And here is the log from the 1.0.1 version (it works flawlessly):

No repository file or test is named. Start by reproducing the remote-debug configuration from launch.json and compare the setBreakpoints GDB requests and sourceFileMap handling between cpptools 1.0.1 and 1.1.2; done means breakpoints in test.c bind successfully with the Windows-to-Linux source mapping.
