Ok.
The invalid reads/writes are concerning though, if you want to try

I still have the same problem on my wheezy system, the only difference
to sid is that I have libc6 2.13-37 instead of 2.13-38 and an older
version of valgrind.
After upgrading libc6 the crash remains with the MALLOC_* variables set.
The invalid read is there with both new and old valgrinds and
