glibc: inconsistency detected by ld.so

I get this strange error:

Inconsistency detected by ld.so: dl-fini.c: 87: _dl_fini: Assertion `ns != LM_ID_BASE || i == nloaded' failed!

The code used to work before until I rearranged it but I got segmentation fault when calling libc fgets twice or more until this recent error about assertion failed.

Here is the code causing the error:

get_inf :: fn(arg: *u8) -> []string {
    _rcp_file : rawptr = fopen(arg, "r".raw)

    if !_rcp_file {
        printf("error: could not open file: '%s'\n".raw, arg)
        exit(1)
    }

    INF_PKG, INF_VER, INF_REL: string
    rcp_buff_pkg, rcp_buff_ver, rcp_buff_rel: *u8
    rcp_line_pkg : i32 = 100
    //rcp_line_ver : i32 = 50
    //rcp_line_rel : i32 = 10

    INF_PKG.raw = fgets(rcp_buff_pkg, rcp_line_pkg, _rcp_file)
    //INF_VER.raw = fgets(rcp_buff_ver, rcp_line_ver, _rcp_file)
    //INF_REL.raw = fgets(rcp_buff_rel, rcp_line_rel, _rcp_file)

    //INF_PKG_CUT := strstr(INF_PKG.raw, ":".raw)
    //INF_VER_CUT := strstr(INF_VER.raw, ":".raw)
    //INF_REL_CUT := strstr(INF_REL.raw, ":".raw)

    //INF_PKG_TRIM := trimstr(INF_PKG_CUT)
    //INF_VER_TRIM := trimstr(INF_VER_CUT)
    //INF_REL_TRIM := trimstr(INF_REL_CUT)

    fclose(_rcp_file)
    return []string { "hello", "world", "!" }
    //return []string {INF_PKG_TRIM, INF_VER_TRIM, INF_REL_TRIM}
}

In the main function, calling fopen(argv[1]) directly causes segfault. It works if I define like this:

rcp_file: string
rcp_file.raw = argv[1]
_rcp_file := fopen(rcp_file.raw, "r".raw)

When compiling two almost identical codes, this one works:

            value := trimstr(split)
            _meta = Append(_meta, value)
 
           line_num = line_num + 1

        }

        meta := Metadata {_meta[0], _meta[1], _meta[2]}

Am I doing something wrong here? Both versions are opening a text file containing:

PKG:: apkg
VER:: 0.14.0
REL:: 1

lib/apkg.kai :

Metadata :: struct {
    PKG: string
    VER: string
    REL: string
}
