I inserted google-breakpad into my test app. But after application crashes and I get info from the dump, in crashed thread always this:

google_breakpad::ExceptionHandler::WriteMinidumpOnHandlerThread

What am I doing wrong? How can I get usefull crash-place? My "installing code":

VS_ExceptionHandlerDescriptor(std::string dump_path) :
    eh(std::wstring(dump_path.begin(), dump_path.end()), NULL, DumpCallback, NULL, true) {
}

My crash-part code:

   void doCrash()
{
    delete reinterpret_cast<char*>(0xFEE1DEAD);
}

int main()
{
    bool installed = VS_ExceptionHandler::InstallExceptionHandler("C://Users//fetterless/Desktop");

    doCrash();
    return 0;
}

UPD1: I Found that the dump from the same crash-program from different computer has different info. From First dump useless as above, on another it shows exactly needed stack and place. What is wrong with this thing?

UPD2: Answer below helped me. I want to add that you can install Cygwin and use it's minidump_stackwalk to produce usefull stack-trace. If you don't want install it and need just stuff for decoding dump, here is archive in which you can find minidump_stackwalk.exe and all needed dll's for it. I took them from my installed Cygwin. minidump_stackwalk archive

I am experiencing the same on some of the Windows machines. Interestingly, Windows 10 works fine for me whereas Windows 7 and 8.1 give results similar to yours. I can only conclude that the problem lies with the stack-walker (minidum_stackwalk.exe or one of the Cygwin dlls). The symbol files and the .dmp file are OK. I actually coped the symbols and the .dmp file from one such problematic Windows machine and was able to generate nice correct call stacks on my Linux box. So, you can also use this as a work-around. But a solution has to come from the Google guys.
