wm.c: fix invalid read error #4

Closed daniellockyer closed 7 years ago

setup() would malloc based upon the size of conf.groups, which would be 0 as load_defaults() hadn't been called yet. As a result, change_nr_of_groups() (at line 1350) would cause an invalid read of size 1 as group_in_use has size 0.
