So we need to understand why that crashes.

> tcache_get (tc_idx=0) at malloc.c:2951
> 2951	malloc.c: Datei oder Verzeichnis nicht gefunden.
> (gdb) bt
> #0  0x00007ffff549a7be in tcache_get (tc_idx=0) at malloc.c:2951
> #1  0x00007ffff549a7be in __GI___libc_malloc (bytes=16) at malloc.c:3058

Once again, all the crashes are inside memory-allocation functions,
which suggests some kind of memory corruption.  Did someone try to run
this scenario under valgrind?
