Comment (by cypherpunks):

 gold throws that error instead of generating (potentially exploitable?)
 code which leads to runtime segmentation fault instead of preemptible
 symbol (if it got preempted) in that case. Yes, this is how x86 Linux
 works. To put some light on it: https://software.intel.com/en-
 us/blogs/2010/11/10/limit-performance-impact-of-global-symbols-on-linux/
 It seems, Linux developers are generally
 [https://github.com/opencv/opencv/issues/10229 shocked] and don't know
 what to do with it, even in [https://dxr.mozilla.org/mozilla-
 esr52/source/security/nss/lib/util/templates.c#123 Mozilla].
