I'd like to reproduce the bug.
Just want to chime in: Don't assume _anything_ about symbol names - they are
extremely complicated and with C++ templates can be extremely long:
nm -a libQt5WebKit.so.5.6.0 | cut -d' ' -f 3 | awk '{ if (length($0) > max)
{max = length($0); maxline = $0} } END { print maxline; print length(maxline)
}'
