Introduction

Goldendict-ng has provide an option to build the application with breakpad

CONFIG+=use_breakpad to enable this feature.

Currently only Windows release has built with breakpad support,for other platforms , you can enable the feature manually.

How to analyze the dump created by breakpad.

When a crash is encountered, a dump file is generated under the folder crash.Take the dump file as a.dmp for following example.

1. dump_syms.exe GoldenDict.pdb > GoldenDict.sym The content of GoldenDict.sym is like this:

MODULE windows x86_64 904B2C52C1EC411D9D0271445CAD6DCD2 GoldenDict.pdb
INFO CODE_ID 645510C96CC000 GoldenDict.exe

2. create a folder such as symbols and a series of folders like this:

GoldDict.exe
a.dmp                 (A)
symbols
└─GoldenDict.pdb    (B)
    └─904B2C52C1EC411D9D0271445CAD6DCD2   (C)
         └─GoldenDict.sym

• A this is the dump file
• B this is a folder name
• C this folder takes the name from the first line of GoldenDict.sym file

3. anlaysis the dump file like this

minidump_stackwalk.exe  -s a.dmp symbols > a.txt

4. check the a.txt file to find the possible crash reason. usually it will point to the actual crash line number of the source code.
