Subject: apache2handler/SIGSEGV with apache2 (prefork)
From: lists@block-online.eu (Oliver Block)

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)
{
        TSRMLS_FETCH();
        if (PG(expose_php)) {
                ap_add_version_component(p, "PHP/" PHP_VERSION);
        }
}

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 TSRM_UNSHUFFLE_RSRC_ID(rsrc_id)         ((rsrc_id)-1)
#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.

Best Regards,

Oliver
