The base group is not brought into range and, therefore, using it as an array
index crashed the X server. Also, at this place, we should ignore locked
groups, but not latched groups. Therefore, use sum of base and latched groups,
brought into range.
Reproducible with:
key <FK07> {
type= "ONE_LEVEL",
symbols[Group1]= [ NoSymbol ],
actions[Group1]= [ LatchGroup(group=-1, clearLocks) ]
};
And hitting F7 will exceed the group level and access arbitrary memory.

The X server uses this directory to store the compiled version of the
current keymap and/or any scratch keymaps used by clients. The X server
or some other tool might destroy or replace the files in this directory,
so it is not a safe place to store compiled keymaps for long periods of
time. The default keymap for any server is usually stored in:
X<num>-default.xkm
where <num> is the display number of the server in question, which makes
it possible for several servers *on the same host* to share the same
directory.
Unless the X server is modified, sharing this directory between servers on
different hosts could cause problems.
