How to use khash in a new thread

[kellabyte]

I'm not looking for locking or a lock-free implementation of khash (although that would be nice!)

I hate it declared as this at the top of the .c file:

KHASH_MAP_INIT_STR(string_hashmap, hw_route_entry*)

In the .h file I have this:

extern void* routes;

Later on I spawn a new thread, and inside the new thread I do the following

void set_route(void* hashmap, char* name, hw_route_entry* route_entry)
{
    routes = kh_init(string_hashmap);
    int ret;
    khiter_t k;
    khash_t(string_hashmap) *h = hashmap;
    k = kh_put(string_hashmap, h, strdup(name), &ret);
    kh_value(h, k) = route_entry;
}

The kh_put() call segfaults with the following:

Program received signal SIGSEGV, Segmentation fault.
0x000000000041a390 in __ac_X31_hash_string (s=0xffffffffb0000950 <Address 0xffffffffb0000950 out of bounds>)
    at lib/haywire/src/haywire/khash.h:387
387     khint_t h = (khint_t)*s;
(gdb) bt

    at lib/haywire/src/haywire/http_server.c:34

I'm pretty new to C, is there something I need to do to make this work in a separate thread? It works fine if I don't use a thread. I'm not sure why there's a problem because I'm calling all the khash methods mentioned above in the same thread.

Any help would be greatly appreciated :)

Upon some further review I found the problem and it was outside of khash. The error was leading me down the wrong assumption. Please close this :)

Thank you for a wonderful library.
