Crash server (JSON_Stringify, JSON_SaveFile) [Linux] #9

Open continue98 opened 1 year ago

continue98 commented 1 year ago

Hi, crash server with JSON_Stringify. Code: 

// global var
new Node: g_node_leaders_list_json = Node:-1;
// some SA-MP callback (for example OnPlayerConnect)
static buf[82_000];
if (JSON_Stringify(g_node_leaders_list_json, buf) == 0)
{
    // useful logic
}
buf[0] = '\0';
// in main/OnGameModeInit
g_node_leaders_list_json = JSON_Object();
JSON_SetArray(g_node_leaders_list_json, "leaders", JSON_Array());
JSON_ArrayAppend(g_node_leaders_list_json, "leaders", JSON_Object(
    "fraction_id", JSON_Int(f_info[i][f_id]),
    "fraction_name", JSON_String(f_info[i][f_name]),
    "fraction_leader_name", JSON_String(f_info[i][f_leader_name])
    )
);

also I can't reproduce this problem on blank gamemode, but I tried to do it without other plugins (only pawn json was included), later I will try to include all the plugins that are used in the real gamemode. Also see: https://github.com/Southclaws/pawn-json/issues/7

Southclaws commented 1 year ago

It looks like SSE is failing in a hash table library called hashbrown. I'm not really sure what the cause is from the trace though. Do you know if your target system is capable of 128 bit SSE registers?
