You need to turn off stripping (which strips debug information from your
programs), re-emerge the mythtv ebuild, and attempt the same steps below.
That should give a better call stack. You enable nostrip by putting
nostrip in the FEATURES line in your /etc/make.conf

Subject: Re: Updated gentoo, now everything mythtv segfaults
I've tried to do a backtrace but when I follow the instructions, I don't
get any information from gdb. Just a list of addresses. I did compile
with debug on and release off.
