Open C::B;
In start page, I clicked "Create a new project";
I choose "Console Application", clicked "Go";
In wizard:
I clicked "next";
selected "C", clicked "next";
in "Folder to create project in:" field, I put "C:\", in Project title, I put "crash_test" (the project folder don't exist yet), clicked "Next";
clicked "Next" again;

Project created.

Then I clicked the gear icon to build the executable. When it finish building the program, I set a breakpoint on line 6 of main.c "printf("Hello world!\n");", clicked "Debug" menu, and then "Start".

The program runs until it ends, the breakpoint is ignored.

Well if I do it exactly the way you described it works fine here. ???

However - what you didn't tell: Did a full re-build solve your problem?
Compiler logging: Settings->Compiler & Debugger->tab "Other"->Compiler logging="Full command line"

Neither "rebuild" nor "clean and build" works. Same result.  :-\

Hello,

I just have the same problem.
After set my project on a new computer, Code::Blocks was not stopping on break point.
The problem was my project path have an accent.

What is your project path? Is there any space or accent?

Hope it can help!

(Sorry for my bad english)

This may cause the gdb problem, so avoid using space or other non-alphabetic chars in the path.

Please give us (post) the full debug log here.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

It's in the first post:
Can you show me the whole "full build log", see:
http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28errors%29#Q:_How_do_I_troubleshoot_a_compiler_problem.3F

Already posted too:
Have you checked this in you full build log?

See here how to enable it: http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28errors%29#Q:_How_do_I_troubleshoot_a_compiler_problem.3F

here's the full build log:
Code
-------------- Build: Debug in wordwrap ---------------

mingw32-gcc.exe  -IC:/prjs/wordwrap -c main.c -o obj/Debug/main.o
mingw32-g++.exe  -o bin/Debug/wordwrap.exe obj/Debug/main.o   
Output size is 24,54 KB
Process terminated with status 0 (0 minutes, 7 seconds)
0 errors, 0 warnings
 

Should the flag appear here? Why is it not appearing?

This log message is wrong, it should have -g option. So, you need to adjust the build options. Or, you can create a simple "hello world" project from the project wizard and test again.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.

Did you read the entire topic? All the things you asked are already posted (including this step) o.o

I can't find ways to help you because you are the only guy who has such strange issue. :)
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.
