Segmentation fault when hiredisSetAllocators by jemalloc about hiredis HOT 2 CLOSED

You're overriding all of the allocation functions to the jemalloc variants but then using libc's strdup.

The program is crashing here:

Which is when hiredis is freeing a string duplicated with hi_strdup.

If jemalloc doesn't have je_strdup then just wrap it like so:

char *je_strdup(const char *s) {
    char *dup;
    size_t len;

    len = strlen(s);
    dup = je_malloc(len + 1);
    if (dup == NULL)
        return NULL;

    memcpy(dup, s, len);
    dup[len] = '\0';

    return dup;
}

hiredisAllocFuncs myfuncs = {
    .mallocFn = je_malloc,
    .callocFn = je_calloc,
    .reallocFn = je_realloc,
    .strdupFn = je_strdup,
    .freeFn = je_free,
};

Going to close the issue since it's not a bug in hiredis but I'm happy to answer any further questions.
