PHP Bug Type: Date/time related
Bug description: SIGSEGV during date parsing with new timelib
Description:
------------
I found a second problem with our PHP installation. Sometimes, not
everytime, the server crashes with sigsegv when parsing date/times. I
cannot reproduce the crash, I only can post the code that most times crash.
Reproduce code:
---------------
This code crashes not always, but often. The $mindate initially contains
as noted in the core dump: 1998-01-01
This is enetered by a user any may look different. The code is used to
fomat any input from the users to an ATOM timestamp.
$mindate=new DateTime($mindate,new DateTimeZone('UTC'));
$search->dateTimeCoverage->min=$mindate->format(DateTime::ATOM);
Expected result:
----------------
The server should not crash.
Actual result:
--------------
Core was generated by `webservd -d
/pangaea/webserver70/https-panwebserver/config -r /pangaea/webserve'.
Program terminated with signal 11, Segmentation fault.
