Actually this bug occurred when I recompiled emacs from source with --with-xwidgets support.

This means your Emacs executable is stripped, which unfortunately
means we cannot use the backtrace you posted.  If you installed Emacs
from some distro, does that distro offer a separate "Emacs debug"
package that you could install?  If it does, please install that and
try again running the addr2line command after that.
