like below fixes the issue I wrote a program that takes lexicographically ordered strings and performs the next lexicographically ordered permutation of those strings, ex: , fixed by changing line,
from:
code :
m = malloc((n + 1) * sizeof(int));

Does that help This intensly smells like a memory management corruption happened prior to this call to malloc().
The corrupted memory management data then made this call to malloc() fail.

hop of those help? I'm a beginner in C and am having memory allocation problems. I checked the related discussions. I should probably use Valgrind, but till the time I learn how to use that, I'm posting the problem here. , your problem
code :
void main()
int main()
int k=half;
int k=half+1;
while((j<=half)||(k<=y)) 
while((j<=half)&&(k<=y))
return C;
for(i=0;i<size;++i){
    A[x+i]=C[i];
}
free(C);
return A;

With these it helps I am going through the cs50x course, doing speller check program. In my fourth implementation of this program I've ran into malloc problem. This time I decided to implement a binary tree. I've read a lot of threads about this problem and checked my code for several times, but I still can't understand what I'm doing wrong. Problem appears in the recursive function that loads dictionary into ram. , In function ld_bin_tree() you have
code :
struct node* new_node = malloc(sizeof(node));
struct node* new_node = malloc(sizeof(struct node));

I wish this helpful for you I recently started learning C and was writing some application, I am getting this error which I have never seen before and which apparently am getting when I am mallocing
code :
Thread *t = malloc(sizeof(Thread *)); 
Thread *t = malloc(sizeof(Thread));

seems to work fine So Im doing so Matrix calculations/conversions right now and now an assertion error showed up. , You have corrupted malloc's heap, most likely:
code :
uint32_t *rowchange =  (uint32_t*)malloc(ROWS+1 * sizeof(uint32_t));
 uint32_t *rowchange =  (uint32_t*)malloc((ROWS+1) * sizeof(uint32_t));
 uint32_t *rowchange =  malloc((ROWS+1) * sizeof(*rowchange));
