JFTR: This is Squeeze's version of libapache2-mod-php5.

Some additional observations which may help to hunt down this bug:

The segfaults do not happen on asdfasdf (which is kfreebsd-amd64), so
it seems to be either a problem on kfreebsd-i386 only or depends on
the actual configuration of the Apache.

I happen to be playing with a kfreebsd install and I can confirm that
apache segfaults. However, I'm going to need some help here,
k{trace,dump} are not to be the easiest tools to debug this problem.
From a quick look at the trace and it seem it is not segfaulting in
php's code, so I'm not even sure it's a bug in php (perhaps it's just
exposing a bug elsewhere.)

PHP itself does work as the test suite passes (well, not at 100% but
that's not something kfreebsd-specific).

Cheers,

Please could you try to rebuild php5 with "PHP5_COMPAT=yes" in 
debian/rules ?

On kfreebsd-i386, the off_t is 64 bit under all configurations,
but ino_t is 32 bit under standard
and 64-bit under "-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64".

According to build logs,
apache is configured without these flags, but php5 with them.

It does help.

On both kfreebsd-i386 and kfreebsd-amd64:

#define __INO_T_TYPE            __U32_TYPE
#define __INO64_T_TYPE          __UQUAD_TYPE

#define __OFF_T_TYPE            __SQUAD_TYPE
#define __OFF64_T_TYPE          __SQUAD_TYPE

#define __RLIM_T_TYPE           __SQUAD_TYPE
#define __RLIM64_T_TYPE         __SQUAD_TYPE

#define __BLKCNT_T_TYPE         __SQUAD_TYPE
#define __BLKCNT64_T_TYPE       __SQUAD_TYPE

#define __FSBLKCNT_T_TYPE       __ULONGWORD_TYPE
#define __FSBLKCNT64_T_TYPE     __UQUAD_TYPE

#define __FSFILCNT_T_TYPE       __ULONGWORD_TYPE
#define __FSFILCNT64_T_TYPE     __UQUAD_TYPE

Therefore ino_t is not the same as ino64_t on both platforms.

The fix should be in apr, it really should advertise their
ino_t as unsigned 32-bit type on both kfreebsd-*.

I.e. /usr/include/apr-1.0/apr.h should contain

"typedef unsigned int apr_ino_t" as used to (at least) until 1.2.12-1,
when 020_lfs_ino_t.dpatch got dropped.

After rebuild of php5 against such header, apache responds.

nice work :)

okay, so apr needs to be fixed, and then -release needs to schedule a
binNMU, and in the meantime we (pkg-php) can just sit back and relax then?

"build-rdeps libapr1-dev" lists 25 more packages, how would we go
about having all them binNMUed, contact buildd admins?

No, you ask debian-release.

However,
http://lists.debian.org/20110305204400.24459.21254.reportbug@k.lan
suggests that the majority of packages will already be dtrt and don't
need rebuilding.
