Can't reproduce here, can you try with latest version?

Also if you could disable optimizations and --enable-debug, that would provide more useful info in the backtrace.

I could reproduce with n0.11.1 but not with git head, on x86_64/Debian.

I cannot reproduce with GIT head. For me the ticket can be closed, I will use the head version instead.
