Anything else that might affect this (besides #12263, which was merged
into rc0), i.e., does the same happen with 4.8.alpha{5,6} + #12263 (with
GCC 4.2.4 on Ubuntu 08.04 / `sage.math`), and does my change (on top of
readline-6.2.p1) make the difference?
My current internet connection is quite poor, so I don't know if I can
fully build Sage and experiment on `sage.math` myself.
Otherwise you could try unsetting `LIBRARY_PATH` in readline's `spkg-
install` (with the same configuration as above that segfaulted) and see
whether that makes any difference. I didn't know that `sage-env` sets
`LIBRARY_PATH`, so didn't expect that ''Sage's'' libtermcap might get
picked up despite us intentionally ''not'' using `-I$SAGE_LOCAL/include`
nor `-L$SAGE_LOCAL/lib` in readline's `spkg-install`.
