Subject: RE: [PHP-DEV] PHP 5.2.3RC1 Released
From: thetaphi@php.net ("Uwe Schindler")

I tried PHP 5.2.3RC1 today and the SunONE webserver using the NSAPI plugin
crashed in module startups with a segfault.

This happens because rasmus changed tsrm_virtual_cwd.c to use
get_request_time instead of time() (see changelog of that file). During
module startup the extension browscap tries to open the browscap.ini file
and uses the TSRM functions to do that (because TSRM is used in NSAPI). At
module startup there is unfortunately no request running so the call to the
SAPI routine sapi_nsapi_get_request_time() core dumps because of a missing
server_context.

I think that should be fixed because it affects all multithreaded webserver
SAPIs that supply a get_request_time-function.

Here the core dump:

#0  0xfc939712 in sapi_nsapi_get_request_time (tsrm_ls=0x0) at
/pangaea/install/php-5.2.3RC1/sapi/nsapi/nsapi.c:721
721             return REQ_TIME( ((nsapi_request_context
*)SG(server_context))->rq );
