My backtrace looks suspiciously similar to the backtrace
reported in comment #14. My backtrace is from an
arts client, not from the artsd server, but they do
share lots of common code.
I've tried to debug the problem: something weird happens
in the destructor of a vector<string>, then GDB seems to
get confused by stack/registers corruption. It really
looks like a code generation bug to me.
Reducing a testcase isn't trivial, but I'll try.
