            Bug ID: 5935
           Summary: QVM memset and memcpy return NULL
    Classification: Unclassified
           Product: ioquake3
           Version: GIT MASTER

          Priority: P3

QVM memset and memcpy return NULL, but should return first argument (like
strncpy). However, fixing this will cause mods that use the return to be
incompatible with vanilla q3 and past ioq3 versions.

strncpy was returning incorrect non-zero value in vanilla q3 and fixed in ioq3,
so might be similar issue of mod depending on it not working on vanilla q3.

Should they be fixed or left as is?

Issue is in CL_CgameSystemCalls, CL_UISystemCalls, and SV_GameSystemCalls.
