The list would be most of GRASS.

E.g. G_malloc() calls G_fatal_error() if malloc() fails (although you
probably can't handle that case anyhow). Anything which uses the
environment (database, location, mapset, etc) will fail if $GISRC
isn't set, can't be opened, doesn't contain correct data, etc.

It might (literally) be simpler to list functions which can't call
G_fatal_error().
