Can't print trace details due to memory allocation issues

[mykaul]

gf_print_trace() is calling gf_dump_config_flags() which is calling gf_asprintf(), which is calling GF_MALLOC() that might fail for various reasons and thus we may not get a nice trace, just a loop of failures.

The offending line is:

#ifdef PACKAGE_STRING
    {
        char *msg = NULL;
        int ret = -1;

        ret = gf_asprintf(&msg, "package-string: %s", PACKAGE_STRING);   <<<-----
        if (ret >= 0) {
            gf_msg_plain_nomem(GF_LOG_ALERT, msg);
            GF_FREE(msg);
        }
    }
#endif

I suspect we could replace all that with:

#ifdef PACKAGE_STRING
    gf_msg_plain_nomem(GF_LOG_ALERT, "package-string: " PACKAGE_STRING);
#endif
