I confirm that nickle 2.71-1 from Debian unstable fixes the problem (it
runs properly even with _FORTIFY_SOURCE).
A no-change build of nickle 2.71-1 is available in my PPA:

Hi Michael-
I discussed the problem with the author of nickle (Keith Packard) in
2011-09 and he determined that there were other places in the code that
would trigger the same type of failure at runtime, if presented with
certain inputs. The NewStrString instance is most obvious since it

Karmal, I'd prefer not to just disable FORTIFY_SOURCE. It is a useful
flag. Wouldn't it be better to use strncpy instead of strcpy and such
as indicated on https://wiki.ubuntu.com/ToolChain/CompilerFlags ?
I'm looking into a patch that does that. But you mention multiple

This patch just disables _FORTIFY_SOURCE, which will resolve other
instances of the same problematic construct which appear in other places
in nickle. This patch fixes nickle's crash(es) and is sufficient to
close this bug.

A fixed installable nickle package (built with _FORTIFY_SOURCE disabled) is now

-U_FORTIFY_SOURCE might be the best solution.
