I'm also attaching a log from valgrind (without the extra memcpy checker).

... and this is without the checker (see messages from ld.so):

I have noticed that the crash is influenced by my memcpy overlap checker (a lib that's preloaded and deterministically crashes the program if memcpy overlaps). This is with the checker in place:
