That's what it's saying, and this was introduced by the fix for: https://sourceware.org/bugzilla/show_bug.cgi?id=20019 But I think this new behaviour is in itself a bug. It isn't reasonable to expect any library that calls longjmp() to link -lpthread just in case it might end up coexisting with another library that does. (The fact that libpthread defines longjmp is arguably a bug in itself, but one that we are stuck with.) p.
