QWindow Program on QT Creator won't run

I have made a program on Qt Creator which builds without errors. But when I try to run it, I get the following in my output pane. Can anyone please tell me what this means/how to fix this? I would appreciate any help.

&"warning: GDB: Failed to set controlling terminal: Invalid argument\n"

Some source code would be nice. It looks like you're trying to delete something twice.

This important line is this:

glibc detected * * * /home/test/Documents/Wave-build-desktop/Wave: double free or corruption (!prev): 0x000000000060b580 *

If you cant catch this problem in the debug then you can analyze the backtrace you just posted to find which function in your program caused this. first do nm ./NameOfYourProgram to get the list of symbols. The list of symbols also displays the address of each function. The addresses in your backtrace will be greater or equal to the symbol addresses. The functions you need to look at in your backtrace are:

/home/test/Documents/Wave-build-desktop/Wave[0x405359]
...
/home/test/Documents/Wave-build-desktop/Wave[0x4042b9]

the addresses here are: 0x405359 and 0x4042b9. You can then step through the function you found and stop at 0x405359 and you will find the exact line in your code where the exception occured.
