Need help fixing a *** buffer overflow detected *** error
Hi,
I'm trying to debug a c program written by someone else and I haven't had to debug c in a long time and nothing this complicated so I'm a bit of a noob. I'm really lost. Please help.
I compile the program with the command
cc -Wall -O2 -g debug_my_stack_noday_cv.c -o debug_my_stack_noday_cv -lfftw3 -lm
and get the error *** buffer overflow detected ***
The output from GDB is:
(gdb) run all_list /media/Elements/ANT/data_HLP/STACK/ 20
Starting program: /media/Elements/ANT/progs_HLP/STACK/debug_my_stack_noday_cv all_list /media/Elements/ANT/data_HLP/STACK/ 20
