ASAN detects memory leak in PARSE_SCFG_STRING

[MasterAler]

Что делал:

extern "C" {
// clang-format off
#define SCFG_APP_CONFIG(XX)                                                    \
XX((input),         SCFG_STRING, 'i', SCFG_NO_DEFAULT, "input video path")     \
/**/
// clang-format on
#include "scfg/scfg.h"
}

int main(int argc, char *argv[])
{  
// init config
if (!scfg_init(argc, argv))
    exit(1);
return 0;
}           

Собрал c ASAN, получаю:

Ругается на scfg/scfg.h:36

#define PARSE_SCFG_STRING(name, val) cfg.name = strdup(val ? val : "")

Предложения: не клонировать строку.
