I've now added -D_GLIBCXX_USE_CXX11_ABI=0 to my local pan package [1] and
it starts up reliably again, irrespective of $CWD.

This turned out to be a fluke: when built against the new ABI pan simply
crashes on startup "sometimes", though it works "most of the time" and
when the $CWD is set to ~.pan2.
