Comment 3 Petr Gajdos 2015-01-05 13:41:52 UTC

Relevant code is run for ZTS build:

#ifdef ZTS
        tsrm_mutex_free(ht->mx_reader);
        tsrm_mutex_free(ht->mx_reader);
#endif

ZTS build can be turned on via --enable-maintainer-zts, but we do not enable it and it is off by default.


checking whether to enable thread-safety... no
