Debugging with GDB (September 2007)

Chapter 22: Reporting Bugs in GDB 325
• A patch for the bug.
A patch for the bug does help us if it is a good one. But do not omit the necessary
information, such as the test case, on the assumption that a patch is all we need. We
might see problems with your patch and decide to fix the problem another way, or we
might not understand it at all.
Sometimes with a program as complicated as GDB it is very hard to construct an
example that will make the program follow a certain path through the code. If you do
not send us the example, we will not be able to construct one, so we will not be able
to verify that the bug is fixed.
And if we cannot understand what bug you are trying to fix, or why your patch should
be an improvement, we will not install it. A test case will help us to understand.
• A guess about what the bug is or what it depends on.
Such guesses are usually wrong. Even we cannot guess right about such things without
first using the debugger to find the facts.
