Can you recompile with debug info, provoke the bug, then attach a
debugger (GDB) and obtain a stack backtrace?

To obtain the trace, run (replace /path/to by /usr/local/sbin or
wherever it ends up in Gentoo):

	gdb /path/to/dnsmasq $(pidof dnsmasq)

Wait until GDB has started

then type:

	backtrace full
