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:

/pangaea/install/php-5.2.3RC1/sapi/nsapi/nsapi.c:721
721 return REQ_TIME( ((nsapi_request_context
*)SG(server_context))->rq );

> The first release candidate of PHP 5.2.3 is now available for testing

> http://downloads.php.net/ilia/php-5.2.3RC1.tar.bz2 (md5sum:

>
> The release comes a bit sooner then anticipated as it is needed to
> address a regression introduced by 5.2.2 in relation to
> RAW_HTTP_POST_DATA handling. I'd like to keep the release cycle as
> short as possible so we can get this version out ASAP. I'd like to
> ask everyone to try this release against their code and/or test suits
> and report any new problems if there are any. If there are no new
> issues I will move to the final release within 1 week.
>
> I'd also like to ask all developers to refrain from making major
> commits or non-bug-fix commits for the next week to the 5.2 branch.
