Segfault problem with --enable-maintainer-zts

Hello, I am writing an open source extension (http://github.com/crodas/phplibtextcat/tree/master). Now I want to add a function that used global variables to set default values, but when I compile it with thread safe enable, it crashed, this is what I do: In php_textcat.h: #ifdef ZTS     #include "TSRM.h" #endif ZEND_BEGIN_MODULE_GLOBALS(textcat)     int ngram_limit;     int threshold;     int max_results; ZEND_END_MODULE_GLOBALS(textcat) ZEND_EXTERN_MODULE_GLOBALS(textcat) #ifdef ZTS     #define TCG(v) TSRMG(textcat_globals_id, zend_textcat_globals *, v) #else     #define TCG(v) (textcat_globals.v) #endif In the php_texcat.c ZEND_DECLARE_MODULE_GLOBALS(textcat) PHP_FUNCTION(foobar) { /* here it crash */ TCG(ngram_limit) = 1; } Probably I am missing something, I read the documentation, I've seen on extension that does that, as the soap, but still I cannot figure out what I am missing.
