i'm not familiar with Calc addins, but in general UNO based extensions
are supposed to work with newer versions as well (unless using
unpublished APIs that actually are changed, which is AFAIK quite rare).

that sounds like an LO bug; extensions are not supposed to crash LO;
please file in bugzilla and attach a backtrace if you can.

i think by now it is mostly for historic reasons.
until 5 years ago or so g++ and libstdc++ regularly changed ABI, so OOo
could not rely on the needed version being available on Linux systems.
but now libstdc++ seems to be stable, so i guess we could get rid of it
in LO4 (it also causes problems with gdb python-fu).

i don't know where the bundled libstdc++ comes from and why it's outdated.
