Unsolved Breakpad analyzing crash report
-
Hi,
I integrated breakpad to my Qt 5.7 MSVC2013 app using this tutorial: https://github.com/JPNaude/dev_notes/wiki/Using-Google-Breakpad-with-QtI obtained stack trace for the crashing thread using minidump_stackwalk.exe:
Thread 0 (crashed) 0 ntdll.dll + 0x6a28c eip = 0x77c7a28c esp = 0x0053f45c ebp = 0x0053f4cc ebx = 0x0053f5ec esi = 0x00000000 edi = 0x00000414 eax = 0x00000000 ecx = 0xfee1dead edx = 0x00760000 efl = 0x00000206 Found by: given as instruction pointer in context 1 KERNELBASE.dll + 0xf4521 eip = 0x758c4522 esp = 0x0053f4d4 ebp = 0x0053f4e0 Found by: previous frame's frame pointer 2 MyApp.exe!google_breakpad::ExceptionHandler::WriteMinidumpOnHandlerThread(_EXCEPTION_POINTERS *,MDRawAssertionInfo *) + 0x66 eip = 0x00a0e277 esp = 0x0053f4e8 ebp = 0x0053f5bc Found by: previous frame's frame pointer 3 MyApp.exe!google_breakpad::ExceptionHandler::HandleException(_EXCEPTION_POINTERS *) + 0xa3 eip = 0x00a0d8e4 esp = 0x0053f500 ebp = 0x0053f5bc Found by: call frame info with scanning 4 KERNELBASE.dll + 0x195cef eip = 0x75965cf0 esp = 0x0053f528 ebp = 0x0053f5bc Found by: call frame info 5 ntdll.dll + 0x9d510 eip = 0x77cad511 esp = 0x0053f5c4 ebp = 0x0053fd28 Found by: previous frame's frame pointer 6 ntdll.dll + 0x63029 eip = 0x77c7302a esp = 0x0053fd30 ebp = 0x0053fd38 Found by: previous frame's frame pointer
This is useless stack trace as it doesn't show stack trace at the time the crash occured (it occured in buggyFunc() mentioned on that page).
I found several topics about exactly this issue, without any solution. So, it there anyone who was able to sucessfully analye breakpads crash report and can give me any advise? Or is there another crash reporting plugin for Qt (preferably some where analyzing crashes is a little less complicated than with breakpad).

@MartinD Do you have more than one thread in your app?

Yes, but they are some system threads. The crash occurs in this thread (you can see it is marked as "crashed").
