Configure Call Stack

You can allow the debugger to generate a call stack trace (unwind the stack) when no debug symbols are loaded. By default, only top-most stack frame will be shown if no debug symbols are loaded.

You can enable it by checking the Call stack unwinding without debug symbols box in the Debug Configuration editor (see Launching the Debugger).

Alternatively, you can enable it by setting the following environment variables:

  1. Open the script located at <install-dir>\system_​debugger\<version>\env.d\win32\*-isysdbg-env.bat.

  2. Add or uncomment the line:

    set ISYSDBG_DBGHELP_PERMISSIVE_MEM_ACCESS=1
    
  3. Additionally, you can change the call stack size. See an example below:

    set ISYSDBG_DBGHELP_STACK_SIZE=0x1000
