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.

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).

[stahta01]

THE BAD OPTIONS DID NOT SET THEMSELVES!!!

Learn how to use your Tools! Its a poor worker who blames their tools for their problems.

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.

Maybe you're running the old (backup) executable?

mingw32-g++.exe -Wall -fexceptions -g -march=corei7-avx -O3 -Wfloat-equal -Wmissing-include-dirs -Wswitch-enum -std=c++11 -Wfatal-errors -Wall -IC:\GnuWin32\include -c "D:\__GNU analyze\biomechanics.cpp" -o obj\Debug\biomechanics.o
...
Process returned -107374195 (0xC000001d)   execution time: 3.682 s

The error-code could be caused by an unhandled exception (illegal instruction?). Does your CPU support AVX instructions? If not, remove the option '-march=corei7-avx' (and -O3 for debug builds).

[zachris]

I'm not running an old backup executable -- I do not back up the executable.

My CPU does support AVX instructions, and this option has been in place for both the working a non-working versions of the code. Nonetheless, I tried switching off that option. It does not make a difference in the outcome.

The bottom line here is that I do not (did not) change anything with CodeBlocks. I merely edited the program code and even removed the edits. The code then compiles, but the program does not run.

[BlueHazzard]

what was your exact command when you compiled it with command line, so that it worked?

[stahta01]

what was your exact command when you compiled it with command line, so that it worked?

FYI: They are likely linking to very old binary that might NOT work with a newer version of MinGW GCC.
