--- Comment #6 from Georg Koppen <gk at torproject dot org> --- Alright, thanks. So, what happens with r215527 is that checking for dlopen() working properly in the configure script is not enough anymore to decide whether one needs -ldl needs to get added explicitly if address sanitizer is enabled. If it is not enabled the dlopen() check is still sufficient. If one uses dlsym() for instance instead the check for needing -ldl is working as before. I still don't understand exactly why this is needed but I guess this is a thing which needs to get fixed on the Mozilla side. Sorry for the noise.
