Minidump stack trace

Hello.
I’m getting a not full stack trace on sentry. But when I use minidump_stackwalk.exe locally, the stack trace is OK.
For example. On sentry I have this:

  • Qt5Core QConfFileCustomFormat::~QConfFileCustomFormat() qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\xml\qxmlstream.h:77

  • MyApp Components::receive_message(QString const &) myapp\components.cpp:179

  • Qt5Core QMetaObject::activate(QObject *,QMetaObject const *,int,void * *) qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\kernel\qobject.cpp:3602

  • Qt5Core QMetaObject::activate(QObject *,int,int,void * *) qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\kernel\qobject.cpp:3740

But it should look like this:

  • MyApp MyWidget::receive_message(QString const &) myapp\mywidget.cpp:347

  • Qt5Core QConfFileCustomFormat::~QConfFileCustomFormat() qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\xml\qxmlstream.h:77

  • MyApp Components::receive_message(QString const &) myapp\components.cpp:179

  • Qt5Core QMetaObject::activate(QObject *,QMetaObject const *,int,void * *) qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\kernel\qobject.cpp:3602

  • Qt5Core QMetaObject::activate(QObject *,int,int,void * *) qt-everywhere-opensource-src-5.8.0\qtbase\src\corelib\kernel\qobject.cpp:3740

So, sentry lost a few last steps.

Maybe some frames got inlined by the compiler optimizer ? 5 frames in debug but only 4 frames in release builds ?

Nope, both examples are from release build. Also I got these stack traces from the same dmp file. Just first I got after uploading to sentry, second - locally with minidump_stackwalk.exe.

There’s something called ‘CFI’ (Call Frame Information ?) that might not be used by sentry to compute the backtrace.

@kosh543 I’m seeing this same issue, our minidump traces are incomplete as well:

you can see that the trace in sentry does not have as many frames as the screen cap of the minidump analysis in Visual Studio.

You can see it bit more clearly in this trace,
here is Sentry’s Raw view:

and the Visual studio stack trace from the minidump analysis:

You can see in the Visual Studio Trace, it goes all the way out to main, which is what i’d like to see in Sentry.

@bsergean did you ever find a solution for this?

No sorry …
