Package: gnuplot
Version: 4.4.0-1
Severity: normal
I tried to visualize a ping to google.de in the following way:
ping -n google.de | perl -nlE '$| = 1; my ($req, $ttl, $time) = ($_ =~
/icmp_req=([0-9.]+) ttl=([0-9.]+) time=([0-9.]+)/); say "$req $time"' | dd bs=1
of=/tmp/ping.dat
The gnuplot file now looks like this:
plot "/tmp/ping.dat" with lines
reread
When starting gnuplot with this file, it first works for some time
(not deterministic), then hangs. When running it in gdb and breaking
when it hangs, I get the following backtrace:

strace also says that it hangs when writing to a pipe (fd 9).
