Subject: libc6 2.3.5 ldconfig segfaults on powerpc oldworld

Package: libc6
Version: 2.3.5-6
Severity: serious
Architecture: powerpc

Subject says it: while upgrading from a rather dated testing install
(around Apr. 05) with libc6 2.2.5-11.8 to current testing, a number of
things went wrong.

Most notably, upon unpacking libc6 2.3.5-6, the libc6 postinstall failed
with ldconfig segfaulting. This error, in the middle of an upgrade that
required Force-LoopBreak, left me unable to recover normally. I forced the
upgrade to proceed hoping some other package yet to be installed would
restore normal ldconfig function, to no avail.

Unpacking the old 2.2.5-11.8 ldconfig, however, fixed my system perfectly.

Synopsis:

broken ldconfig: from libc6 2.3.5-6 (perhaps earlier versions are also
affected)

working ldconfig: from libc6 2.2.5-11.8

kernel version: 2.2.20-pmac (Debian package, unknown version)

/proc/cpuinfo:
processor : 0
cpu : 750
temperature : 0 C
clock : 233MHz
revision : 2.1
bogomips : 467.44
zero pages : total 0 (0Kb) current: 0 (0Kb) hits: 0/628 (0%)
machine : Power Macintosh
motherboard : AAPL,Gossamer MacRISC
L2 cache : 512K unified pipelined-syncro-burst

Please advise how to further debug this (gdb won't help, and the
disassembly of both binaries differ too much to give any meaningful info).
