Re: jemalloc SEGV problem

[Channa <channa.kad%gmail.com@localhost>]

Hi,
Yes i included
All these header files.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char *ptr;
ptr=malloc(10);
strcpy(ptr,"hello");
printf("%s\n",ptr);
return 0;
}

But i am not able to understand where exactly is the problem to use jemalloc.c

Since in the jemalloc.c code i have not modified much apart from the
things i mentioned in my prev mail.

Thanks in Advance,
Channagoud
