Segfaults on tor-0.2.12-alpha and tor-0.2.0.34

[Phil]

This is driving me nuts. tor compiles fine but segfaults soon after starting. I have googled and found similar complaints but no solution.

I tried tor-0.2.12-alpha after tor-0.2.0.34 showed this problem since the changelog to the unstable versions refers to fixing a segfault on starting.
But unstable also shows exactly the same problem. By contrast, v0.1.2.18 built on dsl and run without these issues some time ago, but that is quite old.

Details: tor-0.2.0.34 and tor-0.2.12-alpha compile fine on Damnsmalllinux  using gcc-3.3.5 (old I know).  Installed in /opt/tor against libevent-1.3e and openssl-0.9.8g which were also built and installed in that prefix.  libc is also old - think Debian Woody.  Not running in daemon mode.

Here is what is is printed to the terminal:

How do I fix this?
