getgroups called with incorrect size #169

Closed wfvining closed 7 years ago

wfvining commented 7 years ago

getgroups() is called from push_groups4() with the length of the buffer in bytes. Length should be number of gid_ts that will fit in the array.

I have added a fix here: d2ab92b2, but need to test before it can be merged into master.
