Hi,
Guys sorry if it is a wrong group.
I am analysing the Apple crash report.So I launched my application and tried to forcibly (kill -11 pid) crash the application.The app crashed and even the Apple crash report got generated.
The crash report says Thread 1 crashed, but when I go through the stack trace of Thread 0 I see sigtramp is being received by Thread 0.Is this correct report?
How is the thread received signal is different from the thread that got crashed as per the report ?Any help or suggestion would be of great help.
I have given below the crash report.The highlighted line shows that signal was received by Thread 0 but the crash was happened on Thread 1.I was crashing the application forcibly by sending signal 11 from the command prompt multiple times.There I am confused or may be way I am interpreting is incorrect.
