Using SoftBench Debugger
Debugging C++ Programs
Chapter 7226
However, if your program contains static objects, the constructors for
those objects must be invoked before main(). By the time the debugger
pauses in main(), the constructors have already completed.
If you need to debug these constructors, you must tell DDE to pause
before calling them. This can be accomplished by executing the DDE
command "property system -on". When you set prop sys, DDE
pauses at the very first assembly instruction of the program. You can
then step into the constructors. You should either place the prop sys
-on command in a .dderc file, or issue the command through the
"Debugger Input" input box and rerun your program.
When you pause at the first instruction, DDE does not yet realize you are
executing a C++ program. This can result in any C++ breakpoints being
lost. If you want to retain your C++ breakpoints across executions,
execute the DDE command "prop lang c++" before rerunning your
program. This gives DDE the information it needs to retain your
breakpoints.
When you finish debugging your static constructors, issue "prop sys
-off" and "prop lang default" commands. This returns DDE to
normal debugging mode and uses less CPU resources.
