 Forums >>  IDA Pro  >>  Exception handling

Topic created on: June 26, 2008 04:32 CDT by mori .

Hi all,

I'm trying to debug an application, logging all function calls which an application performs.  Effectively, start app, set function trace, perform task, turn off function trace.

However frequently the application raises exceptions..  I don't care about them, I just want to pass on the exception.

Often a dialog comes up asking if it should deal with the exception directly.  However I have set those exceptions not to "stop" the application and "pass to application".

IDA keeps on stopping execution, and I need to pause and continue to kick it going again.

The breakpoints in question are:
EXCEPTION_SINGLE_STEP
EXCEPTION_BREAKPOINT

Anyone be able to help me?

Debugger options -> [x] Stop on breakpoint instruction. just uncheck this flag, however, if the app uses exceptions, this probably would not help. IDA-Pro debugger doesn't handle/pass exceptions properly.

mori, there was a similar discussion about exception handling when debugging with IDA in the hex-ray forums.

Thanks I'll check it out.
Nez: yeah agreed.  Doesn't appear to handle exceptions very well.
