Hello, I am getting a SIGSEGV when compiling php-5.2.2. gdb breaks up at the if statement of the following function static void php_apache_add_version(apr_pool_t *p) {

        if (PG(expose_php)) {

} It only occurs when --enable-maintainer-zts is used. main/php_globals.h: # define PG(v) TSRMG(core_globals_id, php_core_globals *, v) extern PHPAPI int core_globals_id; #else # define PG(v) (core_globals.v) extern ZEND_API struct _php_core_globals core_globals; #endif TSRM/TSRM.h

#define TSRMG(id, type, element)        (((type) (*((void ***) tsrm_ls))

[TSRM_UNSHUFFLE_RSRC_ID(id)])->element) GDB tells me that core_globals_id == 0 which leads to an index of -1 -- if I interpret the results correctly.

Either GDB is wrong or your build is badly broken. core_globals_id is initialized in main/main.c, line 1491 *rsrc_id = TSRM_SHUFFLE_RSRC_ID(id_count++);

#define TSRM_SHUFFLE_RSRC_ID(rsrc_id)       ((rsrc_id)+1)
