Hello,
This simple C program
test.c
#include <mongoc.h>
#include <stdio.h>
mongoc_client_pool_t *client_pool;
void mongodb_new()
{
mongoc_client_t *client;
const char *uristr = "mongodb://127.0.0.1/";
mongoc_init ();
client = mongoc_client_new (uristr);
if (!client) {
fprintf (stderr, "Failed to parse URI.\n");
}
}
void mongodb_delete()
{
mongoc_client_pool_destroy(client_pool);
mongoc_cleanup();
}
int main (int argc, char *argv[])
{
mongodb_new();
//mongodb_delete();
}
compiled as:
gcc ./test.c -o test -lmongoc-1.0 -I/usr/local/include/libmongoc-1.0 -I/usr/local/include/libbson-1.0
throws segmentation fault when run under Valgrind:
valgrind --leak-check=yes ./test
See output below:
