For those who want to test the git version, the commits are:

    last good: a61813ccdd4b7bcc81932317e1360fda6c79962d
    first bad: 6b2f7c5fd7a3e465f4e2662b1e5bd2c9d5cce8f8

Don’t forget to delete the cache.

I suspect I found the troublesome changes. The problem vanishes
if I revert this modification to font-map.lua:

    -local separator   = S("_.")
    -local other       = C((1 - separator)^1)
    -local ligsplitter = Ct(other * (separator * other)^0)
    +local ligseparator = P("_")
    +local varseparator = P(".")
    +local namesplitter = Ct(C((1 - ligseparator - varseparator)^1) * (ligseparator * C((1 - ligseparator - varseparator)^1))^0)

and then further down:

    -                local split = lpegmatch(ligsplitter,name)
    <...>
    +                local split = lpegmatch(namesplitter,name)

For convenience I repeat the link to the changeset:

Best,
Philipp
