Is this GTK related ? Core dump

[dragos2]

This is related to http://ubuntuforums.org/showthread.php?t=1416475
After fixing that path, the GUI starts fine and when I try to load a file it dumps the core.

GTK version installed


ii libgtk2.0-dev 2.12.9-3ubuntu5
This is the backtrace:

Please, post the code. It's impossible to debug that...

EDIT: Don't post the whole thing. Post the load_file.c source file.

[dragos2]

Please, post the code. It's impossible to debug that...

I can't post the whole program, there are 10 source files and 4 headers.

And the backtrace and dump does not say where the problem may be.

I will try to post isolated and relevant code but any idea from the dump and backtrace what
file can it be ?

[pbrane]

I would say that this is your problem:


*** glibc detected *** ./gcc_costGUI: free(): invalid pointer: 0x00007f355aacfda0 ***

Somewhere in gcc_costGUI you are calling free() on a pointer that is not valid. One that has either not been initialized or one that has already been free()'d. You could always do this:


if (pointer)
free(pointer);


Maybe look at gcc_costGUI for pointers that you allocate memory for and look at pointers that are allocated by any called functions. Are you calling load_file() in gcc_costGUI()?

Uf... I edited my post and seems you were too fast for me :P

Ok, like I said above, post the load_file.c file.

[gnometorule]

As others said above, problem should be in load_file.c per your core dump. Compile with -g option (as you already do); then set a break point at or some lines before line 47 in that file (where your program seems to hop off) using gdb. Then single step through from that breakpoint, checking vars around there at each step, in particular whichever pointer is used. That should probably isolate your problem. Repost if that doesn't solve it, with code of that file - although i am not sure that you can solve the issue with just the source code for one file. Gl.
