Are you sure? V seems to like the debug symbols read from /usr/lib/debug/lib32,
else there would have been a "CRC mismatch" after each "Reading debug
info", right?
My problem building earlier was because I forgot to rerun autogen.sh.
Builds fine from source now.
I wrote a little test for the problem.
On Ubuntu 8.04, neither 32 nor 64 bit works.
On Ubuntu 8.10, 64 bit works, but 32 bit doesn't.
It's possible I've borked all my own systems somehow.
If you have an Ubuntu 8.10 64 bit x86_64 system with valgrind installed,
could you run this script and let me know what it says?
Thanks...
