I'll try to reproduce the FTBFS on a porterbox later today.
Awesome. Let me know if there's anything I can do to help.
As promised, here's gdb backtrace:

The line that triggers crash is:
nn_chunk_size (((struct nn_chunkref_chunk*) self)->chunk) :
Here dereferencing fails catastrophically, because the pointer is
unaligned (self=0x25351).
