I don't really have interest in investigating further to check/verify
these claims , but this might be an answer :
21:26 <@kevlarman> oh and it's not nearly as simple as "just use malloc()"
21:27 <@kevlarman> the structure with the extensions string is passed
to the cgame and ui modules,
which are usually run in a sandbox without a
malloc() implementation
21:28 <@kevlarman> and even if they had it, the client has no way of
communicating to them how much
memory they should allocate for it to write the
extension string
21:29 < shining> kevlarman: why isnt there all freedom to change that ?
21:30 <@kevlarman> shining: because then it won't work with q3 anymore
