std::exception is not giving stack trace

[Sendil kumar]

Hi All,

Problem Stetement:I have a problem in getting stack trace when I ues std::exception.

In my code, I allocate virtual memory for certain kind of processing and will throw the std::bad_alloc exception if memory could not be allocated. I have never handled the bad_alloc, so, what I expect here is a stack trace from windows showing the excact location where the exception was thrown. But, to my surprise it gives only the windows Runtime Error message.

But...

When I assign a value to a null pointer, in this case it is access violation exception, the windows handles the uncaught exception and gives me a stack trace of what I expected.

I don't know what I'm missing to implemet to get a stack trace for std::exception.

Please any body could help me to solve this issue.

Catching an exception cannot be stack traced. Since the stack is unwound before you get to the catch block, there's no stack to trace.

The null pointer does not produce a catchable exception. All it produces is an access violation and the stack is left alone. You can trace this.

I don't catch the std::exception, so, I guess the error stack will definitely have all the needed information. I throw the uncaught exception so let it be handled by the OS and give me a stack trace in html format file, but, it just gives me a message saying "Run time Error. The Application is Requested to close"

My doubts are...

1) Can we either get the stack trace for all std::exceptions ?

2) If the case 1 is possible, then how to do it?

I don't believe you can get a stack trace for a catchable exception.
