I'm trying to find the cause of some 503 errors I'm observing during a
load-test.
Running "varnishlog -r /path/to/logfile -o TxStatus 503" causes varnishlog
to segfault with the following backtrace:
Program received signal SIGSEGV, Segmentation fault.
0x00000000004015cb in h_order (priv=0x0, tag=SLT_SessionOpen, fd=6843503,
len=0, spec=1, ptr=0x774777 "o") at varnishlog.c:130
130 if (ob[fd] == NULL) {
(gdb) bt full
