#39428 [Opn->Bgs]: compiling in largefile support causes immediate segfaults

ID: 39428 Updated by: tony2001@php.net Reported By: seanius at debian dot org -Status: Open +Status: Bogus Bug Type: Apache2 related Operating System: Debian GNU/Linux PHP Version: 5.2.0 New Comment: Of course it will segfault, as those flags change size of the structs used in Apache. And if Apache was compiled with -D_FILE_OFFSET_BITS=64 and PHP was NOT, you end up with different structures and this apparently won't work. You need either compile them both with those flags or remove the flags for both.
