它只会在某些机器上崩溃，而我的老板正站在我身后！

有谁知道如何调试这样的错误?

hi
Recently I take over an old C++ product from the guy who left the company, It''s a big one and I am still learning about it.

It makes me crazy, I got this error[^] and I can''t find where the problem is.

It only crashs in some of the machines, and my boss is standing behind me!

anyone knows how to debug such an error?

thank you

解决方案

This problem is usually easy to solve. Almost 100% of certainty that this is result of "infinite" recursion or mutual recursion:
http://en.wikipedia.org/wiki/Recursion[^],
http://en.wikipedia.org/wiki/Mutual_recursion[^].

Such problems can be resolved in a very systematic way using the debugger. First, you observe where the exception is thrown. Put a breakpoint before it happens and use the debugger window "Call stack". You will see where the calls come from. Find out the reason for infinite recursion and devise a correct condition of exit from recursion. Usually, the bug can be found very quickly if you combine debugging with simple logic.
