Hi all,

I've experienced the bug mentioned in the title. No matter which
browser - tried with Chromium 60, Firefox 54, Midori, Epiphany,
QupZilla, even Dillo, but all of the browsers crash dwm when opening
these links in them (disabling javascript does not help):


I use Arch Linux. Only dwm is affected, the links open with no problem
under i3. I've tried with the dwm package from the Arch repo (which
was built using the unmodified config.h I guess), cloning the git repo
and compiling myself with the vanilla config, but nothing changes: the
result is a crash when opening these links.

Some logs (using the dwm package from Arch repo):

After opening links with Chromium:
