I finally got a backtrace of pinger with gdb:

That's 'delete CurrentDebug' in the debug.cc:
void
Debug::finishDebug()
{
assert(TheDepth >= 0);
assert(CurrentDebug);
if (TheDepth > 1) {
*CurrentDebug << "}-" << TheDepth << std::endl;
} else {
assert(TheDepth == 1);
_db_print("%s\n", CurrentDebug->str().c_str());
delete CurrentDebug;
CurrentDebug = NULL;
}
--TheDepth;
}
Which was reported in bug #728144 wherein Amos Jeffries says the bug had
been forwarded to http://bugs.squid-cache.org/show_bug.cgi?id=2656,
however that upstream bug is from 2009 dealing with "Pre-Init TZ env"
which I've confrimed is already patched in squid3 3.4.8-6.
