git checkout crashes after server being updated to Debian X86_64

[Raffael Reichelt <raffael.reichelt@gmail.com>]

Hello! 

I have a serious problem with git, After my provider had updated to a X86_64 architecture git crashes with various memory-related errors. This is happening remote when pushing to the repository from my local machine as well as trying it on a shell on the server itself.

This are the error-messages:

fatal: Out of memory, realloc failed
fatal: recursion detected in die handler
fatal: recursion detected in die handler

or
fatal: unable to create threaded lstat
fatal: recursion detected in die handler
or
fatal: unable to create threaded lstat
*** Error in `git': double free or corruption (fasttop): 0x0000000000a8ade0 ***
fatal: recursion detected in die handler
Aborted

It’s obviously not a problem of the repository - happens with all of them. I think it is also not a question of size - happens with a 80M Repository as well as with a 500M one.

Any way: did a 

git fsck
Prüfe Objekt-Verzeichnisse: 100% (256/256), Fertig.
Prüfe Objekte: 100% (56305/56305), Fertig.

git gc --auto --prune=today —aggressive
git repack

Additionally I played around some config parameters  so my config now looks like:
[http]
    postbuffer = 524288000
[pack]
    threads = 1
    deltaCacheSize = 128m
    packSizeLimit = 128m
    windowMemory = 128m
[core]
    packedGitLimit = 128m
    packedGitWindowSize = 128m
    repositoryformatversion = 0
    filemode = true
    bare = true

I am running 
git version 2.1.4
 
on
Linux infongp-de65 3.14.0-ui16196-uiabi1-infong-amd64 #1 SMP Debian 3.14.73-2~ui80+4 (2016-07-13) x86_64 GNU/Linux

Anyone out there to help me getting out of this trouble?

Regards,
Raffael
