Segfaults with eglibc-2.16 on ARM v6 (hardfp)

[Stephan Raue <mailinglists at openelec dot tv>]

Hi,

after upgrading my embedded distribution from eglibc-2.15 to 2.16 i get 
libc related segfaults with every program. Because this distro uses 
shell based init scripts and busybox, which also segfaults provides the 
shell i cant boot into the system with eglibc-2.16. With eglibc-2.15 all 
is working.

I have tried to boot in to a system with eglibc-2.15 and copy the 
eglibc-2.16 filessystem to a writabable location in /storage:
    root ~ # LD_LIBRARY_PATH=/storage/system/lib/ 
/storage/system/bin/busybox
    Segmentation fault

if i replace /storage/system/lib/libc.so.6 with the one from eglibc-2.15 
system:
    root ~ # LD_LIBRARY_PATH=/storage/system/lib/ 
/storage/system/bin/busybox
    BusyBox v1.20.2 (2012-07-19 08:32:53 CEST) multi-call binary.

    ...

how i can debug this system to get more infos to provide to find the 
issue? i have GDB and STRACE installed on the system, if i run gdb:
    root ~ # gdb /storage/system/bin/busybox
    GNU gdb (GDB) 7.4.50.20120716
    ...
    (gdb) set environment LD_LIBRARY_PATH=/storage/system/lib/
    (gdb) run
    Starting program: /storage/system/bin/busybox
    During startup program terminated with signal SIGSEGV, Segmentation 
fault.
    (gdb) bt
    No stack.


thanks for your help
