zig调用c接口奔溃

[zhang-chuanfeng]

比如c的接口如下：

char* HTTPUTIL_Post(const char* url, const char* body, const char* appkey, const char* secret, int timeout, int* dataLen);
``

zig代码
```zig
const std = @import("std");
const c = @cImport({
    @cInclude("HttpUtil.h");
});

pub fn main() void {
    const szUrl = "https://10.188.0.101:443/artemis/api/resource/v1/regions";
    const szBody = "{\"pageNo\": 1,\"pageSize\": 20}";
    const appkey = "26395532";
    const secret = "mDXrfXuGRzNW0aqUkzgD";
    var len: c_int = 0;
    std.debug.print("11111111", .{});
    var data: [*c]u8 = null;
    data = c.HTTPUTIL_Post(szUrl, szBody, appkey, secret, 15, &len);
    std.debug.print("2222222", .{});
    if (data == null) {
        std.debug.print("33333333", .{});
        std.debug.print("post fail", .{});
        return;
    }
    std.debug.print("4444444444", .{});
    std.debug.print("{s}", .{data[0..@intCast(len)]});
    std.debug.print("555555555", .{});
    _ = c.HTTPUTIL_Free(data);
}

崩溃结果：

链接libc就正常了
