Modification causes program to crash
zachris:
I am running Code::Blocks version 13.12 rev 9501 on MyOperatingSystem
Windows7. The compiler I use is MinGW32 (the one that installed with Code::Blocks)
When I ...
I have a set of code that use to compile and run. But now, it compiles but does not run. I do not know why.
Description of problem.
I can copy a old (backup version) of the code to my programming directory. I load this project into Code::Blocks and it compiles and runs just fine. However, if I modify anything in the code (such as merely adding a comment) the code will compile, but the program will not run.
I am new to Code::Blocks (been using it for about 2 weeks without problems as I develop this program). The problem I describe started yesterday morning.
I accept that this is probably a problem with how I am using Code::Blocks, but I cannot think of anything that I am doing differently today from what I was doing last week. If there is something on the wiki, or this forum, that describes this problem I have not found it (perhaps because the description of the problem defies a simple title).
Build log for when the program compiles and but does not run:

... but none of them worked.
I have an old version of the code that I copy entirely into my “programming” directory. This version of the code will compile and run just fine. However, if I modify anything – even adding a comment – the code will compile, but fail to run.
scarphin:
Did you try to run the compiled executable from the command line (cmd.exe)? Does it work when run from the command line?
zachris:
Yes, it compiles and runs from the command line.
This is the way I am progressing with the program. But having to go to the command line to compile and run defeats the purpose of an IDE.

Did you use the exact some options?
EDIT: Most people never use these two options "-g" "-O3" at the same time.

zachris:
I am not sure if I used the same options. I do not know how to set them in Code::Blocks.
However, since I do not know how to alter them I am fairly sure that I did not change options within Code::Blocks.
Still, this compiling and running from the command line does not explain why I was able to compile and run before, but now can seemingly compile but cannot run (or only run in a way that causes a crash).
